Subject: [vtkusers] How to draw a raster text strings at a 3D positon?
Message-ID: <7A48A19D30984951B965AA7741F13CDE@chensqPC>

Hi, vtkers.
I can draw vector text strings at any 3D position. But it changes its size when zooming. This is undesirable sometimes.
Can anyone suggest me how to draw a fixed-size text string (e.g. raster text strings) at a 3D postion?
Thank you in advance.
Sincerely Chen.

Hi there,

I've attached a python script and a small pickle with associated data.

A code snippet, from the file, is found below and some debug output is
found below.

My code is a quick hack of a working use of vtkImageData() from the mailing
list archives.

I've taken out the original author's (thanks quentan) data source and put
in place my pickle file.

When I run the script I get a window, but nothing visible in it except a
black back-ground.


I haven't looked in detail at the code, but it looks like you're trying to
use a vtkPolyDataMapper to visualize a vtkImageData. vtkPolyDataMapper is
for visualizing polygonal data. Normally to visualize a vtkImageData (a
volume) you'd use a volume mapper such as vtkSmartVolumeMapper or
vtkGPUVolumeRayCastMapper. Also, in order to do that I think the volume
needs to be > 1 in all dimensions, as VTK interpolates between datapoints
to form a visual voxel.

But I may of course be misunderstanding, I'm somewhat new to VTK myself.

Elvis


I'm not sure if its data representation issues,  viewport/camera issues, or
pipeline issues; I'm open to all three actually - but I think its probably
pipeline... the full extent of which is in the attached script.

The original author has an (n1, n2, n3) matrix generated with a bunch of
trig, but I am using an (n1, n2, 1) matrix that I can view in matplotlib as
an image.  My data numpy array on a grid generated by mlab.griddata.

bscan_grid graphs well, as an image, in other packages, so I believe the
issue is somewhere in the block below(with the missing pipeline).

I was hoping to get a surface plot, or height map of my bscan_grid, with z
mapped onto xy

The attached script has a bunch of debug statements, the output when used
on the attached pickle is underneath the code snippet.

I've stripped the code out and put a subsection below to illustrate my
question, which is how do I get my lovely vtkImdateData objectto chain over
and into the mapper and render my surface?

Thanks,

Nick




data_matrix = bscan_grid   #bscan_grid comes from the attached pickle and

Subject: [vtkusers] Trouble using cx_freeze
Message-ID: <CAPyYnjUnTKo3guj8BKHUAyMGV=uEjjFvonSXQTZUJpLJYR3-Qg@mail.gmail.com>

Hello all,

I'm am using cx_freeze on Windows to create an executable of a Python
Script which includes vtk.
The python script executes fine. Vtk is correctly installed and PYTHONPATH
and PATH variables are set accordingly.

I ran cx_freeze using a setup.py file, which created a build folder with an
executable of the script and the necessary libraries, including the vtk
files necessary for it to run in a "vtk" subfolder. No major problem there.

Double clicking on the .exe file in that folder launchs the program.
Double clicking on the .exe file after temporaly deleting my C:\Python
folder also works.
So at that point I thought my .exe file was indeed "stand alone" and needed
only the subfolders in the build folder (like the vtk one) to work on its
own.

However, when I sent this build folder to a colleague, the execution fails
because of vtk, with message :
Traceback (most recent call last):
File "C:\Python27\lib\site-packages\cx_Freeze\initscripts\__startup_.py",
line 14 in run
File "C:\Python27\lib\site-packages\cx_Freeze\initscripts\Console.pu", line
26, in run
File "PediLoc_Main.py", line 28 in <module>
File "C:\Users\Philippe\Documents\Friz\PediLoc_Result.py", line 109 in
<module>
File "C:\Python27\Lib\site-packages\vtk\lib\python2.7\
site-packages\vtk\__init__.py", line 41 in <module>
File "C:\Python27\Lib\site-packages\vtk\lib\python2.7\site-packages\vtk\vtkCommonCore.py",
line 9, in <module>
Import Error : DLL load failed : The specified module could not be found.

In the vtk subfolder of the build, there is vtkCommonCore-8.0.dll.

So I'm sort of stumped here. The .exe works on my computer, even when I
take out Python juste to see if execution is possible without the python
(and therefore, vtk) libraries.
But not on another computer....

Using VTK 8.0.1, Python 2.7, both my computer and my colleague's one are
Windows 7, 64 bits machines.

Thanks for any insight,
Cl?ment

Subject: [vtkusers] vtkBlending and vtkResliceimageviewer with different
	lookup tables
Message-ID: <1506968252132-0.post@n5.nabble.com>

Hi,
I am trying to set up a pipeline blendng N medial imaging data sets which
may have different lookup tables.
{vtkImageReader2 => vtkImageMapToColors}N => vtkImageBlend =>
vtkRescliceImageViewer
I tried to adapt the examples ImageMapToColors, Colored2DImageFusion, and
CombineImages from /www.vtk.org/Wiki/VTK/Examples/Cxx/ to my needs, but I
probably failed to transfer the data properly into vtkRescliceImageViewer. I
needed
imgViewer2->GetImageActor()->GetMapper()->SetInputConnection(imgBlend->GetOutputPort())
to transfer the LUT information and
imgViewer2->SetInputConnection(imgBlend->GetOutputPort()) to enable browsing
through the slides.
Two input connections look weird and I lost the interactor function to
change the level/window. How are such pipelines supposed to be set up ?

Thanks an advance, Jorg

Subject: [vtkusers] Vector field visualization issue
Message-ID: <1506979600014-0.post@n5.nabble.com>

Dear VTK users, 

I am a novice VTK user and need help, I hope you have some time. 

1. I have created a structured grid and filled it with both vector data (a
velocity field) and scalar data (the velocity magnitude). This is set as
point data. The data is initially in numpy format and converted to vtk using
numpy_to_vtk.

2. I visualize the vector Field using Glyph3D and everything looks great,
both vector direction, scaling, and color mapping is correct. Great so far,
very happy with the results.

Then the issue: 

3. I try to use vkStreamTracer to create streamlines from the exact same
data structure. It seemingly does use the vector field when visualized using
wither polylines or through a tubefilter, but: 
   a) I get strange vertical blocking artifacts, where the streamlines don't
cross (out_of_domain)
   b) The colors mapped are also way off, following the same blocking
artifacts

Any ideas?

Best Regard,
Lasse Lovstakken

I inserted an image to illustrate:

Hi,

I am reading through the vtk textbook and user guide, both available for

I am finding that most of the equation formatting is pretty messed up.
I've tried every pdf reader available, and nothing seems to help.

How do I get well formatted equations?  Am I missing something simple here?

You would need to give me a more specific example for me to help. That
change mostly impacted meshes that use scalar coloring.  But in general the
color on screen is driven by diffuse ambient and specular colors and
properties make sure those are set to reasonable values.

Maybe find a mesh where you see an issue and let me know what the
ambient/diffuse/specular colors and intensities are for the mesh. No
texturing. No backface properties. No scalar coloring. Maybe go from
there...

Subject: [vtkusers] Changes in diffuse properties of material.
Message-ID: <A78A5EB2-B923-4C87-8604-7746B2DD236B@rogue-research.com>

Hi everyone,

    I recently discovered whilst working with VTK master that some meshes are completely rendered dark in colour compared to others; meshes that rely on their material (actor?s properties) are mostly affected. I tracked the occurrence of this change down to the following commit below and was wondering the essence of the change, also if need be how can one replicate the previous rendering behaviour.

- commit 7bc7e58334bcd1eac12adb6db22d6c45cf8fca74
Author: Ken Martin <ken.martin at kitware.com>
Date:   Thu Aug 31 13:08:58 2017 -0400

    update handling of scalar material mode
    
    Previously scalar material mode when used
    with scalars would ignore the ambient and diffuse
    material intensities and when mapping one of them
    set that one to 1.0 while leaving th eother alone.
    This caused lots of odd situations where objects would be
    over illuminated etc or where changing the diffuse or
    ambient seemed to have o impact.
    
    With this change the diffuse and ambient intensities
    are always used. The sclaar simply controls the color
    not the intensity. 


Thanks.

Regards,
   Seun.

Subject: [vtkusers] How to just change the surface appearance of the
	transform object in paraview?
Message-ID: <tencent_1063A28221C498B8176EEE42@qq.com>

Hi, There,


Sorry first, I know this email should sent to the paraview user email-list. But I can't joint it until now. 


I have a triangular sphere surface with two scalars on every point. In paraview, I transform the surface and get two new triangular spheres, see the attachment figure and data. 


I want to change the colormap of the third one, but paraview will also change the first one. So is it possible to just change the colormap of the every surface independently?

Huayi

Hi,
Is there any implementation available in VTK where I can compare two
polydata and know if they are different?

I want to design a function like this

int polydataCompare(polydata1, polydata2)

if they are different the function will return 1 else return 0

Thanks and regards,

Hello

Since you asked on the ParaView ML as well, this can be easilly done in a
ParaView Programmable Filter,
where you could compare all points, cells, point data, cell data and filed
data of the inputs datasets.

Mathieu Westphal

I'm Marco I've just started my phD last week , about computational fluid 
dynamics of polymeric turbulent flow , I would really understand the 
algorithm for write a generic script that given a set of point x,y,z 
construct a file in this format :

# vtk DataFile Version 3.0
vtk output

VERTICES 3 6
1 0

1 2

POINT_DATA 3
SCALARS element float
LOOKUP_TABLE default
8 1 1
SCALARS somefield float
LOOKUP_TABLE default
0.687 0.262 0.185


I have no idea how to set the LINES and VERTICES starting from only a 
number of spatial point ! could somebody help me please ?

Hello

I've included a very simple state file that compare the number of points in
two different datasets.
You can expand the python programmable script to compare anything you want.
You can find examples here :

Subject: [vtkusers] some errors when use vtkTecplotReader
Message-ID: <1507108023045-0.post@n5.nabble.com>

Hi everyone, 
    I am trying to use the vtkTecplotReader to read the *.dat file which is
produced by Tecplot, however, there are always some errors, such as "The
record type ** found in the file is unknown." and "Tecplot zone record
parameter 'STRANDID' is currently unsupported". And if I try to use the
Paraview to read the Tecplot file, the same errors are also existed. So I do
not know how to deal with this, and I wonder if I need to write a new
tecplot reader or is there anyone who has solved these problems. 
  

Thanks. 

Regards, 
Jane

Dear VTK users,


How can I change the scale of the image based on the following code lines :


double center2[3] = {image_vtk->GetCenter()[0], image_vtk->GetCenter()[1], image_vtk->GetCenter()[2]};
        if (image_vtk->GetExtent()[0] % 2 == 1)
        {
            center2[0] = image_vtk->GetCenter()[0] + 0.5*image_vtk->GetSpacing()[0];
            center2[1] = image_vtk->GetCenter()[1];
            center2[2] = image_vtk->GetCenter()[2];
        }

        // Setting camera to view the rendered slice to the whole viewport.
        float xc = image_vtk->GetOrigin()[0] + 0.5*(image_vtk->GetExtent()[0]+ image_vtk->GetExtent()[1])*image_vtk->GetSpacing()[0];
        float yc = image_vtk->GetOrigin()[1] + 0.5*(image_vtk->GetExtent()[2] + image_vtk->GetExtent()[3])*image_vtk->GetSpacing()[1];
        float yd = (image_vtk->GetExtent()[3] - image_vtk->GetExtent()[2] + 1)*image_vtk->GetSpacing()[1];

        float d = camera->GetDistance();
        camera->SetParallelScale(yd);




Kind regards,

Message-ID: <CAE-7VJkSwmPsEL1TxZsQ3W=O8NXJvVC9vtz9Zr+f39F6r=VsPw@mail.gmail.com>

Hi all,

In the test case below, I render one 200x200x2 volume and one
200x200x3 volume, both with the same settings.

The 200x200x3 volume looks as expected (the light gray one in the
attached screenshot), while the 200x200x2 one looks strange (too dark,
and with some kind of gradient artifact).

Is there some limitation on rendering a volume that is only 2 thick in
one of the dimensions? I can understand why a volume of thickness 1
can't be rendered properly, since VTK must have values to interpolate
between, but 2 should be OK right?

Thanks for any help.

Elvis

Subject: [vtkusers] Deprecate Qt4
Message-ID: <CADwGrVoyzX5RuZtsmnDRNX+u+SNJdQWv96kDz-Ss+E-N6+3Eug@mail.gmail.com>

Hi all,
We are working to deprecate VTK use of Qt4.

https://gitlab.kitware.com/vtk/vtk/merge_requests/3300

After this merge request is in, VTK_QT_VERSION will be 5 by default and
you'll get warnings if you switch it to 4 and use VTK with Qt4.

You can silence the warnings using
VTK_LEGACY_SILENT=ON

You can remove all legacy features using
VTK_LEGACY_REMOVE=ON
(You may want to do that if you compile with Qt5, to make sure you don't
use by mistake Qt4 features).

VTK + Qt applications using Qt5 need to use QVTKOpenGLWidget instead
of QVTKWidget that was used for Qt4.

Please make sure that your sampling distance is less than < 2. You can set
the sampling distance manually in the API.

Hi Aashish,

Hm. I don't think it's related to sampling distance. In the test case
I'm not setting sampling distance at all, so I think it should default
to 1, and then be automatically adjusted during interaction.

In any case, even if I amend the test case with e.g.:

    volumeMapper->AutoAdjustSampleDistancesOff();
    volumeMapper->SetSampleDistance(0.2);
    ...
    volumeMapper2->AutoAdjustSampleDistancesOff();
    volumeMapper2->SetSampleDistance(0.2);

The result is the same.

Subject: [vtkusers] Calculate geodesic distance
Message-ID: <1507128228972-0.post@n5.nabble.com>

Hello all,
I woulkd like to calculate, in python, the geodesic distance between two
points on a surface(polydata) with vtkDijkstraGraphGeodesicPath.

But I fail to understand how to do that.

Any help is much appreciated.

Thanks,

My code:

import vtk
cylinder= vtk.vtkSphereSource()
cylinder.SetCenter(0.0, 0.0, 0.0)
cylinder.SetRadius(0.5)

dijkstra = vtk.vtkDijkstraGraphGeodesicPath()
dijkstra.SetInputConnection(cylinder.GetOutputPort())
dijkstra.SetStartVertex(2)
dijkstra.SetEndVertex(10)
dijkstra.Update()

pathMapper = vtk.vtkPolyDataMapper()
pathMapper.SetInputConnection(dijkstra.GetOutputPort())

cylinderMapper = vtk.vtkPolyDataMapper()
cylinderMapper.SetInputConnection(cylinder.GetOutputPort())

pathActor = vtk.vtkActor()
pathActor.SetMapper(pathMapper);
pathActor.GetProperty().SetColor(1,0,0)# Red
pathActor.GetProperty().SetLineWidth(4);

cylinderActor = vtk.vtkActor()
cylinderActor.SetMapper(cylinderMapper)
cylinderActor.GetProperty().SetColor(0,0,1) # (0,0,1) or tomato
cylinderActor.RotateX(30.0)
cylinderActor.RotateY(-45.0)

#distance?

The reason that the lines and vertices are recorded the way they are is probably to save space. In your small example it may not be readily apparent, but once you start to get a semi-large dataset, such as a 3D CFD mesh, it will make much more sense why it is done that way. Just as an example of how you might do this in something like python, here is a script that writes out a circle:


#!/usr/bin/env python3

# -*- coding: utf-8 -*-


from math import *

N = 20


points   = []

vertices = []

segments = []


for i in range(N):

  points.append((0., cos(i*2.*pi/N), sin(i*2.*pi/N)))

  vertices.append((1, i))

  segments.append((2, i, (i + 1) % N))


print("""# vtk DataFile Version 3.0

vtk output

ASCII

DATASET POLYDATA\n""")


print("POINTS {} float".format(N))

for point in points:

  print("{} {} {}".format(*point))

print()


print("LINES {} {}".format(N, 3*N))

for segment in segments:

  print("{} {} {}".format(*segment))

print()


print("VERTICES {} {}".format(N, 2*N))

for vert in vertices:

  print("{} {}".format(*vert))

print()

I'm Marco I've just started my phD last week , about computational fluid dynamics of polymeric turbulent flow , I would really understand the algorithm for write a generic script that given a set of point x,y,z construct a file in this format :

# vtk DataFile Version 3.0
vtk output

DATASET POLYDATA

POINTS 3 float
1.0 0.5 1.5
0.2 0.1 0.8
0.4 0.2 2.3

POINT_DATA 3
SCALARS element float
LOOKUP_TABLE default
8 1 1
SCALARS somefield float
LOOKUP_TABLE default
0.687 0.262 0.185


I have no idea how to set the LINES and VERTICES starting from only a number of spatial point ! could somebody help me please ?

Subject: [vtkusers] Enable or disable pan,
	rotation and zoom on key pressed event
Message-ID: <1507130197973-0.post@n5.nabble.com>

I'm trying to set up a MouseInteractor Class
(vtkInteractorStyleTrackballCamera) handling events to disable pan, zoom, or
rotation. Each of these functions would be enabled or disabled according to
an user's pressed key.
I think the most common way of doing it, is to generate an event handler
function for each different key and, inside it's block setting some flag of
the class vtkRenderWindowInteractor to false or true using a function like
setPan(false) or setPan(true), etc.

But as you may know there's no such function or method on the
vtkRenderWindowInteractor class.
Is my aprroach correct? Does someone have a better idea?

Thank you all.

thanks..I just wanted to make sure that we remove that as one of the
culprit. I am wondering if it is something to do with the geometry (bbox)
or
something to do with some edge case (calculation that is going off because
of very small delta). Although in the past we have tried very think volumes

Is it possible for you to send a sample dataset to us?

Subject: [vtkusers] Solidify vtkPolyData
Message-ID: <1507156428979-0.post@n5.nabble.com>

Hello everyone,

does vtk include a similar filter or is there a method like the Solidify
Modifier in Blender ( link
<https://docs.blender.org/manual/en/dev/modeling/modifiers/generate/solidify.html> 
)?

Basically I have a non watertight vtkPolyData containing faces which I want
to solidify by adding opposite faces on their backs.

Thanks a lot, Sebastian

Yikes, a VTK class shouldn't present user interface elements like that, but
rather leave it up to the application.

Unfortunately, I don't know if that is possible from outside vtkAVIWriter.
See
https://msdn.microsoft.com/en-us/library/windows/desktop/dd756791(v=vs.85).aspx
how you can choose a different default from within vtkAVIWriter.cxx.

Subject: [vtkusers] Performance comparison between VTk7.0.0 and VTK8.0.1
Message-ID: <CA+UkBty4ygteBf8v763MDUUMxZOw9sT-kLSNjm2H-iT8F9ofyw@mail.gmail.com>

Hello folks,

I was doing a performance comparison between the VTK 7.0.0 with OpenGL1 and
SMP as sequential against VTK 8.0.1 with VTKm, OpenGL2 and SMP with OpenMP
but I saw no difference of the rendering process at all. I think it's a bit
strange, I read some articles in Kitware about the vantages to use VTKm and
OpenGL2 but in my simple test there is no difference. Does anyone know what
it's happening? Or Do I need to activate or do something different ?

Attached on this e-mail is the code which I used.

In terms of performance what are the vantages in VTK 8.0.1 when compared to
VTK 7.0.0?

Thanks in advance.

Best Regards,

> Got it, thanks!

Although I'm not familiar at all with the code, I suspect this is what
happens with my 200x200x2 volume:

In void vtkOpenGLGPUVolumeRayCastMapper::vtkInternal::ComputeCellToPointMatrix()
{
  this->CellToPointMatrix->Identity();
  this->AdjustedTexMin[0] = this->AdjustedTexMin[1] =
this->AdjustedTexMin[2] = 0.0f;
  this->AdjustedTexMin[3] = 1.0f;
  this->AdjustedTexMax[0] = this->AdjustedTexMax[1] =
this->AdjustedTexMax[2] = 1.0f;
  this->AdjustedTexMax[3] = 1.0f;

  if (!this->Parent->CellFlag) // point data
  {
    float delta[3];
    delta[0] = this->Extents[1] - this->Extents[0];
    delta[1] = this->Extents[3] - this->Extents[2];
    delta[2] = this->Extents[5] - this->Extents[4];

    float min[3];
    min[0] = 0.5f / delta[0];
    min[1] = 0.5f / delta[1];
    min[2] = 0.5f / delta[2];

    float range[3]; // max - min
    range[0] = (delta[0] - 0.5f) / delta[0] - min[0];
    range[1] = (delta[1] - 0.5f) / delta[1] - min[1];
    range[2] = (delta[2] - 0.5f) / delta[2] - min[2];

    this->CellToPointMatrix->SetElement(0, 0, range[0]); // Scale diag
    this->CellToPointMatrix->SetElement(1, 1, range[1]);
    this->CellToPointMatrix->SetElement(2, 2, range[2]);
    this->CellToPointMatrix->SetElement(0, 3, min[0]);   // t vector
    this->CellToPointMatrix->SetElement(1, 3, min[1]);
    this->CellToPointMatrix->SetElement(2, 3, min[2]);

    // Adjust limit coordinates for texture access.
    float const zeros[4] = {0.0f, 0.0f, 0.0f, 1.0f}; // GL tex min
    float const ones[4]  = {1.0f, 1.0f, 1.0f, 1.0f}; // GL tex max
    this->CellToPointMatrix->MultiplyPoint(zeros, this->AdjustedTexMin);
    this->CellToPointMatrix->MultiplyPoint(ones, this->AdjustedTexMax);
  }
}

delta[2] = 1 ==> min[2] = 0.5 ==> range[2] = 0

So the scale factor in the third dimension will be 0 in
CellToPointMatrix, right? I guess this could be what accounts for the
strange rendering?

Could/should this code be updated to take into account when the extent
delta is just 1, so that volumes 2 data points thick can be rendered?

Do you already have a benchmark code to test the differences of performance
between this two versions?

Because I'm thinking to migrate a software to vtk8 + vtkm + opengl2 + tbb
or openmp, but I have to show to my colleagues the advantages regarding the
performance of this new version compiled with these flags, to see if will
be prioritize or not.

I will try to do what you said as well. Thanks.

I've only tested it briefly, but this seems to give the correct
rendering even with a 2 point thick input:

diff --git a/Rendering/VolumeOpenGL2/vtkOpenGLGPUVolumeRayCastMapper.cxx
b/Rendering/VolumeOpenGL2/vtkOpenGLGPUVolumeRayCastMapper.cxx
index 8767bd0..88bbcba 100644

   if (!this->Parent->CellFlag) // point data
   {
     float delta[3];
-    delta[0] = this->Extents[1] - this->Extents[0];
-    delta[1] = this->Extents[3] - this->Extents[2];
-    delta[2] = this->Extents[5] - this->Extents[4];
+    delta[0] = std::max(2, this->Extents[1] - this->Extents[0]);
+    delta[1] = std::max(2, this->Extents[3] - this->Extents[2]);
+    delta[2] = std::max(2, this->Extents[5] - this->Extents[4]);

     float min[3];
     min[0] = 0.5f / delta[0];

This ensures the texture does not collapse into 0 when the extent
delta is 1. Would you consider this a correct fix?

Subject: [vtkusers] VTK OpenVR issue and questions
Message-ID: <500335EB-9FA1-4A2B-88DE-CC3AAF8F67B0@icloud.com>

Hi, 
I?m quite new to VTK coding ; I downloaded and compiled the last git master version and I would like to know :

1- When using Volume Rendering (such as in Medical4 example) in OpenVR, no volume is displayed at all in the VR Headset. When I try to add for example legacy .vtk files (in polydata) to the scene, the whole rendering is flickering, and the volume rendering is not displayed, but the polydata are displayed with flickering and lagging.

2- When using the OpenVR rendering, it is possible to clip the whole scene (choice from user?s menu).
How could I :
	2.1 - Map a slice from an ImageData Volume to the clipped scene ?
	2.2 - I have a data volume (binary raw, displayed after marching cube) and a polydata file (legacy .vtk) ; I would like to clip the volume only, not the poly data inside the OpenVR rendering.How could I do this ?

Thanks for your help :-)

For (1) Make sure you set yourRenderWindow->SetMultiSamples(0) before the
first render,  that could be the issue. Not sure about flickering and
lagging but if you have a nvidia card make sure you open the nvidia control
panel and set your preferred graphics processor to be the high performance
nvidia processor and set vertical sync to Off (I forget which it is). Apply
those settings and then try again.

2) the clipping should clip whatever is in the scene. Changing it to clip
only some actors is not supported. You would need to look at the code in
vtkOpenVRInteractorStyle.cxx and see how we do the clipping and then use
similar logic in your code.

Thanks we are looking into it, earlier we moved the math from the shader to
a matrix that now we are forming in C++ so at this point we are looking at
the equation carefully. But yes, I thought you may have found a bug.

Thanks for having a look. I suspect my std::max(..) is just a
workaround and not a proper fix.

Me and a colleague had another look, but I think we were both too
tired to figure out if something was fundamentally wrong with the
equations. Too late in the day :)

No worries...so we just checked the math the cell to point offset matrix
seems to be right but the delta seems wrong. Can you change this

>     delta[0] = this->Extents[1] - this->Extents[0];
>     delta[1] = this->Extents[3] - this->Extents[2];
>     delta[2] = this->Extents[5] - this->Extents[4];

to this

delta[0] = this->Extents[1] - this->Extents[0] + 1;
delta[1] = this->Extents[3] - this->Extents[2] + 1;
delta[2] = this->Extents[5] - this->Extents[4] + 1;

Thanks,

Hi ,

I am trying to build VTK using ANGLE with openglES. I made some
modifications to the CMake. I set the OPENGL_HAS_EGL to on and set the
values of accompanyed EGL and opengl values correctly.

While building the vtkRenderingOpenGL2 project, I ran in compilation error
that some gl functions are defined in both glew and gles files.
My question is shall I remove glew from the CMake file?
I read that glew can not be built with opengl es.
How can I remove this module?.

Regards
Elhassan

Here is the merge request we are testing: https://gitlab.
kitware.com/vtk/vtk/merge_requests/3413

It will require probably some more work to ensure correctness at other
places but this is a start that should fix your problem.


Thanks! That's one of the things me and my colleague tried out during our
session here. It will fix my specific problem, but I think we found that it
gave ill effects in other cases.

I'll continue the discussion on the MR, I have a testcase I can share when
I'm home (on the bus atm).

Look at vtk_glew.h.in that is what gets included. For ANDROID builds it
skips the inclusion of glew. So follow that same logic I think.

Subject: [vtkusers] ANN: VTK Book Examples
Message-ID: <CADZJ4hP64JwujJtHH1YjTdEzKFt23oGtE+3doB7Xq7sYH347GQ@mail.gmail.com>

Folks,

We've started an effort to convert all of the examples mentioned in
the VTK Book. This is a works in progress.

Since some of the API's have changed, the new implementations may
differ from those in the book. Also, since Tcl used less frequently,
the examples have been converted to C++. The examples are also
enhanced by newer VTK features, like vtkNamedColors and
VtkSmartPointer.

Each Figure example

1) links to the source code of the new implementation,
2) links to the doxygen documentation for classes demonstrated,
3) shows the original figure caption and,
4) if the example produces an image, links to the full resolution image.
5) If the caption includes a source file reference, e.g. bluntStr.cxx
or rotations.tcl, that reference links to the original source code.

Go to: https://lorensen.github.io/VTKExamples/site/VTKBookFigures/

Figures that have been converted will show an image on the right:

For example see:
https://lorensen.github.io/VTKExamples/site/Cxx/VisualizationAlgorithms/LOx/

Please enjoy this new effort to revive the VTK Figure examples.

Bill

Elvis,

What you said makes sense. I think there might be other places (we have
identified atleast one more) where we are off by one on one axis. If you
can identify some more issues with our fix, ping us and we will sort them
out. Thank you for providing us a edge case and culprit code.

thanks,

A long while ago, I converted most of the VTK Book examples from TCL to
Python, (Sept 2014 to be precise). I still have the converted examples and
notes as to where conversions failed.

No one was interested at the time.

If you want I can zip up the code and send it to you.

Regards

Hi Andrew, I would be very interested in getting a copy of your port.
Please zip and send!

Thanks in advance, I'm working through the book as we speak... those
examples will come in handy.

Here they are. I have left out all the data files to save space.
Please note:
1) They were probably done in Python 2.6.
2) It was for VTK 6.0

As Bill noted it would be a good idea to use vtkNamedColors instead of
colors.py in the Python folder. These conversions were done long
before vtkNamedColors
existed.

Conversion Progress.txt should give you a good idea as to what was done.

Regards
   Andrew

Dear all,

Is there a way to perform fast non-conforming interface projections (cf. 
https://www.unige.ch/~gander/demo.php) between two unstructured grids, 
or even between an unstructured grid and a rectilinear structured grid, 
currently within the vtk library? Cannot find any info on that? Thanks!

Hello community

Is there a way to draw dotted line with the new backend ?

We used something like this before

m_actor->GetProperty()->SetLineStipplePattern( 0xf0f0 );
m_actor->GetProperty()->SetLineStippleRepeatFactor( 1 );

But the doc says it works only for the old backend.
Any other solution ?

Thanks
Simon

Message-ID: <CAHyF3ojp3LMWBHB43NyEhjsJq1aNvTzBxJTY_83nJ8cJquOvbA@mail.gmail.com>

I would like to subdivide a selection of polyData triangle cells based on
location, not metric information.

I can see how this could be possible and found a similar unanswered
question from a few years ago.

given a large mesh, select a small group of cells and subdivide them while
retaining the subdivided and un-subdivided mesh as one mesh in the output.

Hello VTK guys,


I have successfully built VTK8 with Qt5.9.1 using VS 2017. I am trying to follow an example about Qt by CXX, and download CXX and CMake file. By following everything instructed, I opened the generated project and built, but I am faced with some errors, which indicate the relevant header file (.h) is missing.


I googled for a while and did not find a clue. It seems everybody does the same but without the errors. Could anyone shed a light upon what I have missed?


Best wishes,


Chiang

Hi Mike,

Thanks for the prompt reply.

I tried the example of  SideBySideRenderWindowsQt on https://lorensen.github.io/VTKExamples/site/Cxx/Qt/SideBySideRenderWindowsQt/. I got the error

Error (active) E1696 cannot open source file "SideBySideRenderWindowsQt.h" SideBySideRenderWindowsQt d:\develop\C++\projects\QtVTKTest\SideBySideRenderWindowsQt.cxx 1

and some other errors relating to the above error.

I am using vtk8.0.1, Qt5.9.1, and VS2017 on Win 7.

Any further comments?

Best wishes,

Chiang

I have not converted the new VTKExamples to generate proper CMakelists.txt
files for Qt examples. To build the Qt examples you will need to build all
of the examples. The easiest way to do that is to enable the Wiki examples
remote module in your vtk build.

Subject: [vtkusers] Inresolved external for QVTKWidget in VTK-8.0.1.
In-Reply-To: <0d6f851e-674d-5b09-1e8b-542fae4a3795@esi-group.com>

Dear all,

In CMake I generated a solution project of VTK-8.0.1 with Qt5 support 
for MSVS2013. After having run the ALL_BUILD and INSTALL projects with 
the install prefix C:\VTK\8.0.1 in VM2013 I could installed the Win32 
bit binaries of VTK 8.0.1 in that folder. The header files and the 
libraries are located in
C:\VTK\8.0.1\include\vtk-8.0   and
C:\VTK\8.0.1\lib.

I copied the file QVTKWidgetPlugin.dll from the VTK binary folders to 
the plugin folder of QTCreator, which uses QT 5.8 msvs2013 32 bit version.

Then I set the include and library paths and added all the VTK libary 
files from C:\VTK\8.0.1\lib for the linker setting in the project file
of a QT application in QtCreator:

INCLUDEPATH += C:\VTK\8.0.1\include\vtk-8.0

However, if I add a QVTKWidget on the UI file of the application, 
include the file QVTKWidget.h in the header file of the application and 
I try to link it in QtCreator with the 32-bit VTK and Qt libraries, 
MSVS2013 (in the toolchain of QtCreator) sends error messages for 
unresolved external symbols for all the functions/classes belonging to 
the QVTKWidget, such as

distortionpage.obj:-1: Fehler: LNK2019: unresolved external symbol 
"__declspec(dllimport) public: __thiscall QVTKWidget::QVTKWidget(class 
QWidget *,class QFlags<enum Qt::WindowType>)" 
(__imp_??0QVTKWidget@@QAE at PAVQWidget@@V?$QFlags at W4WindowType@Qt@@@@@Z) 
referenced in function "public: void __thiscall 
Ui_DistortionPage::setupUi(class QWidget *)" 
(?setupUi at Ui_DistortionPage@@QAEXPAVQWidget@@@Z)


It seems that the linker could not find the libary for the QVTKWidget 
plugin, which is loaded since I could chose QtWidget from the widget 
list in the UI form editor in QtCreator. I do not see any ABI issue here 
since I use the 32 bit mscv2103 version of Qt and I also compiled and 
linked the 32 bit version of VTK libaries and plugin files with 
MSVS2013. I am wondering if anybody could make VTK-8.1 working with Qt. 
Thanks a lot.

Kind regars,
Zoltan

Zoltan

That's great. Thanks for the help!


I just wonder if there are any docs/tutorials regarding how to program VTK with Qt rather than the examples? Anything fundamental would be very welcome.


Best wishes,


Chiang

Yes, for the time being.

Or you could run the old wiki example

https://www.vtk.org/Wiki/VTK/Examples/Cxx/Qt/SideBySideRenderWindowsQt

The code for the Qt examples has not changed...

Thanks Bill.

Does this mean all examples have to be built during VTK building in order to run them properly? Is this only for vtk 8 or for all legacy versions?

Best wishes,

Chiang

??: Re: [vtkusers] ??: CXX example with Qt

I have not converted the new VTKExamples to generate proper CMakelists.txt files for Qt examples. To build the Qt examples you will need to build all of the examples. The easiest way to do that is to enable the Wiki examples remote module in your vtk build.

I am using vtk8.0.1, Qt5.9.1, and VS2017 on Win 7.

Any further comments?

Hello VTK guys,


I have successfully built VTK8 with Qt5.9.1 using VS 2017. I am trying to follow an example about Qt by CXX, and download CXX and CMake file. By following everything instructed, I opened the generated project and built, but I am faced with some errors, which indicate the relevant header file (.h) is missing.


I googled for a while and did not find a clue. It seems everybody does the same but without the errors. Could anyone shed a light upon what I have missed?

Zoltan,
This is unrelated to the error you are seeing however:

For Qt5 you'll need to use QVTKOpenGLWidget rather than QVTKWidget.  See
https://lorensen.github.io/VTKExamples/site/Cxx/
All examples are converted to Qt5. Also, VTK master has a number of
examples that have been converted to Qt5: Examples/GUI/Qt

Hope this helps,
Dan

Also, when working with VTK, it will be a lot easier to switch to using
CMake instead of Qt project files (QtCreator supports CMake). Look at the
examples Dan linked to. You will have to update the CMakelists.txt file for
Qt. You will probably have to add the following:

FIND_PACKAGE(Qt5Core REQUIRED)
FIND_PACKAGE(Qt5Widgets REQUIRED)

and update the target_link_libraries line(add Qt5::Widget) , e.g.,:

target_link_libraries(QtBarChart Qt5::Widgets ${VTK_LIBRARIES})

Dear Dan,

Thank you for your prompt answer! The problem is that our application 
development is bound to QtCreator and it seems that the Qt5 support of 
VTK provides a plugin file for QVTKWidget and not for QVTKOpenGLWidget. 
Inspecting the example RenderWindowNoUiFile.cxx, I cannot see how 
QVTKOpenGLWidget can be placed in an UI form file even if its class can 
be defined in the C source. In the widget list of QtCreator I have only 
QVTKWidget because of the plugin and no QVTKOpenGLWidget is available in 
it. Thanks four your help.

Kind regards,
Zoltan

Dear Mike,

Thank you very much for your prompt answer. As I wrote to Dan, we have 
to use QtCreator for the development here. Then I have access only for 
qmake and I can edit project files for it. If QVTKOpenGLWidget is the 
only VTK widget class supported for Qt5 then I ave to find out how to 
insert such an object into the UI form file of QT.

Kind regards,
Zoltan

I just added a new example that draws stippled lines. Take a look to
see if it helps...

In Qt Designer you should be able to use QVTKOpenGLWidget by adding first a
QOpenGLWidget and then 'Promote to ...' a QVTKOpenGLWidget. So you can
build the UI of your Qt application this way.

I am not sure what is needed for QtCreator. I don't use that.

Hope this helps,
Dan

Hi Ken,

   I had to take a closer look at how I was rendering my mesh, it seems everything is fine; I was a bit thrown off by the scalar colouring at first and couldn?t really understand the need for the change but on further scrutiny I figured I had to readjust how I was setting my ambient values. Thanks.

Regards,
  Seun

Thanks Bill,

I was able to create a dashed line with this texture trick, thanks.
However, it is difficult to reproduce the same effect than with the opengl1
version. In the the previous version, each created dash had a constant
"lenght" on the screen when you zoom in or out on the actor. With the new
version, the number of dash is the same on the line, no matter how long or
how "zoomed" in it appears on the screen.

In your example, the number of "dash" is controlled by the resolution of
the source, is that correct?
So to achieve the same result, the only solution is to connect a callback
on the camera, and adapt the linesource resolution to the current zoom, no
? Or maybe there is an easier solution ?

Thanks anyway,
Simon

Hi,

Sorry for the double post.
Since the old post of Karthik 
<https://public.kitware.com/pipermail/vtkusers/2010-May/060254.html>, is 
there a way with "vtkDijkstraGraphGeodesicPath" to have the distance by 
GetGeodesicLength() ? How to do otherwise?

Thanks in advance!

My python script:

cylinder= vtk.vtkSphereSource()
cylinder.SetCenter(0.0, 0.0, 0.0)
cylinder.SetRadius(0.5)

dijkstra = vtk.vtkDijkstraGraphGeodesicPath()
dijkstra.SetInputConnection(cylinder.GetOutputPort())
dijkstra.SetStartVertex(4)
dijkstra.SetEndVertex(28)
dijkstra.Update()

weights = vtk.vtkDoubleArray()
size=dijkstra.GetCumulativeWeights(weights)

print size

I obtain for size: none

Hi,

The vtkDijkstraGraphGeodesicPath filter seems to output a sorted point
set along the geodesic path. Hence, a straightforward way of getting
the distance is summing the lengths of each segment that makes up it.
---
pts = dijkstra.GetOutput().GetPoints()

p0 = [0,0,0]
p1 = [0,0,0]
dist = 0.0
for ptId in range(pts.GetNumberOfPoints()-1):
  pts.GetPoint(ptId, p0)
  pts.GetPoint(ptId+1, p1)
  dist += math.sqrt(vtk.vtkMath.Distance2BetweenPoints(p0, p1))

print(dist)
---

Regards

Subject: [vtkusers] Merge polydata surface with cube
Message-ID: <1507792951789-0.post@n5.nabble.com>

I have a relatively flat polydata (like an undulating landscape).
I want to clip asquare section out of it and add a 'base to it so it becomes
a cube where the top side represents the clipped surface.
The new polydata should be watertight.

I have tried adding points for the cube underneath, clipping the surface and
running a Poisson resurface but the edges get rounded, and I would rather
not have to resurface the original data.

Any ideas how I can mount my surface patch in a cube?

Subject: [vtkusers] Size of labels in vtkScalarBarActor
Message-ID: <CA+zyc0XcZ-AgX4EdDJ4Nqj09r7ByzwE1aZoFJerxjXdUs91NnA@mail.gmail.com>

Hello.

I know that this issue was discussed many times before in this list, but I
can't find a way to do what I want. I'm using VTK 7.1.1 (under Windows). So
maybe there were some improvements.

In fact, I'm using vtkPVScalarBarActor which includes some very well
welcomed improvements, but the discussion should apply also to the normal
vtkScalarBarActor.
https://www.paraview.org/ParaView/Doc/Nightly/www/cxx-doc/classvtkPVScalarBarActor.html

The issue is that the size of the labels for values depends on the
viewport. So when the viewport changes the size, the labels also change
their size. Is it possible to avoid this? I would like to set the size of
the labels as constant or at least to define a maximum/minimum size,
because sometimes it gets veeeeery small/big and it is not very pleaseant.

Thank you!

PS:
Here's my code to configure the vtkPVScalarBarActor, in case it's useful...
(I guess there are some calls that are useless):

vtkSmartPointer<vtkPVScalarBarActor> scalarBarActor =
vtkSmartPointer<vtkPVScalarBarActor>::New();
scalarBarActor->GetPositionCoordinate()->SetCoordinateSystemToDisplay();
scalarBarActor->GetPositionCoordinate()->SetValue(20, 20, 0.0);

scalarBarActor->SetAddRangeAnnotations(0);
scalarBarActor->DrawTickMarksOff();
scalarBarActor->UnconstrainedFontSizeOff();
scalarBarActor->AnnotationTextScalingOn();
scalarBarActor->SetFixedAnnotationLeaderLineColor(true);

scalarBarActor->SetOrientationToVertical();
//scalarBarActor->SetWidth(0.1); // width in viewport coordinates
scalarBarActor->SetMaximumWidthInPixels(80);
scalarBarActor->GetLabelTextProperty()->BoldOff();
scalarBarActor->GetLabelTextProperty()->ItalicOff();
scalarBarActor->GetLabelTextProperty()->ShadowOn();
scalarBarActor->AutomaticLabelFormatOff();
scalarBarActor->SetLabelFormat("%.2f");
scalarBarActor->SetRangeLabelFormat(scalarBarActor->GetLabelFormat());
scalarBarActor->SetMaximumNumberOfColors(100);
scalarBarActor->SetNumberOfLabels(5);

scalarBarActor->SetLookupTable(tempLUT); // defined elsewhere, doesn't
matter

scalarBarActor->SetTitle("Displacements");
scalarBarActor->SetTitleJustification(VTK_TEXT_RIGHT);
scalarBarActor->GetTitleTextProperty()->SetFontSize(8);

Fernando,

Because you are using a scalar bar actor from ParaView, I suggest using the
vtkContext2DScalarBarActor. Font sizes are fixed in this scalar bar actor
implementation.

HTH,
Cory

Subject: [vtkusers] DICOM reader and setting bit depth
Message-ID: <1507815532359-0.post@n5.nabble.com>

Hi

I have a problem when reading a DICOM image using vtkDICOMImageReader.

Looking at the result, I get the impression that the depth information is
not applied properly. I'm pretty sure that problem lies on my side. But
could you help me what I do wrong?

Judging from the DICOM header, my DICOM has a signed short depth.
<http://vtk.1045678.n5.nabble.com/file/t341102/Screen_Shot_2017-10-12_at_15.png> 

A slices looks like this in OsiriX:
<http://vtk.1045678.n5.nabble.com/file/t341102/slice-osirix.jpg> 

However, if I open the DICOM image with vtkDICOMImageReader, my result looks
different. Indeed, values lower than 0 and larger than 255 are shown either
black or white, which indicates that the bit depth is cropped beyond the
8bit range.

<http://vtk.1045678.n5.nabble.com/file/t341102/Screen_Shot_2017-10-12_at_15.png> 

Here the code I used for reading: 



It of course could be that the rendering could be set up wrong as well. I
used the  ReadDICOMSeries
<https://www.vtk.org/Wiki/VTK/Examples/Cxx/IO/ReadDICOMSeries>   example
without further modifications.

Help would be appreciated.

Hi,

Always with vtkDijkstraGraphGeodesicPath function, is-it possible to 
constrained the geodesic shortest paths (example 
<http://www.ziegelmann.info/Mark%20Ziegelmann-Dateien/Constrained%20geodesic%20shortest%20paths.htm>)?
and thus to add points beetween the "dijkstra.SetStartVertex(X)" and the 
"dijkstra.SetEndVertex(Y)"?

Thanks in advance!

Frederic

Message-ID: <213331D6-FF74-4476-9C66-F6794CAE898B@contoso.com>

Hello --

I am belatedly updating my program to use vtk 7 or 8 instead of 5.10.   There are some things that I clearly don't understand about the new architecture.

Following https://www.vtk.org/Wiki/VTK/Build_System_Migration, I have added 
    VTK_MODULE_INIT(vtkRenderingOpenGL2);
    VTK_MODULE_INIT(vtkRenderingVolumeOpenGL2);
before any other vtk operations.  (I'm not using cmake, for unrelated reasons.)  

When my program opens a graphics window, I get errors
     ERROR: In /Users/langer/UTIL/VTK/VTK-7.1.1/Rendering/Core/vtkTextActor.cxx, line 113
     vtkTextActor (0x7fb87c83c2b0): Failed getting the TextRenderer instance!
which I can make go away by including
   VTK_MODULE_INIT(vtkRenderingFreeType);
but then I get the message
   VTK is designed to work with OpenGL version 3.2 but it appears it has been given a context that does not support 3.2. 
   VTK will run in a compatibility mode designed to work with earlier versions of OpenGL but some features may not work.
(After that my program crashes, but it may be for unrelated reasons.)

https://www.vtk.org/Wiki/VTK/Build_System_Migration implies that I should use vtkRenderingFreeTypeOpenGL instead of vtkRenderingFreeType, but that doesn't exist.  I get the error
   dyld: lazy symbol binding failed: Symbol not found: __Z45vtkRenderingFreeTypeOpenGL_AutoInit_Constructv
Is there a libvtkRenderingFreeTypeOpenGL.dylib that should be part of vtk?  How do I get it to build that?  It doesn't exist in the directory with the rest of the vtk libraries.

The page https://www.vtk.org/Wiki/VTK/VTK_6_Migration/Factories_now_require_defines looks like it should be helpful, but the links to the helpful mailing list threads are broken.   Does someone know the correct links?

How do I know what modules I should be initializing?  Have I missed something when building vtk?   I'm on MacOS Sierra, using macports to install everything except vtk itself  (although macport's version of vtk is not too terribly ancient, it's built without VTK_USE_X, which I need).

When building vtk, if I leave OPENGL_INCLUDE_DIR, OPENGL_gl_LIBRARY, and OPENGL_glu_LIBRARY set to the default (/System/Library/Frameworks/OpenGL.framework) , the vtk build fails with undefined symbol errors (_glXChooseFBConfig, etc).   So I point them at macports' files (/opt/local/include, /opt/local/lib/libGLl.dylib, and /opt/local/lib/libGLU.dylib).  Then vtk builds but doesn't find OpenGL 3.2.   The Mac does support later versions of  OpenGL-- how can I get vtk to use it?

Many thanks,
       Steve

Hello Frederic,

The options about constrained shortest path can not be found in the
vtkDijkstraGraphGeodesicPath. I don't know it is helpful or not but it
is possible to add points to pass through as some of the constraints.
It works in the following way due to applying vtkAppendFilter
successively to some outputs of vtkDijkstraGraphGeodesicPath.

---
import vtk
import math

cylinder= vtk.vtkSphereSource()
cylinder.SetCenter(0.0, 0.0, 0.0)
cylinder.SetRadius(0.5)

appendFilter = vtk.vtkAppendFilter()
appendFilter.MergePointsOn()

vIds = [4, 12, 23, 28]

p0 = [0,0,0]
p1 = [0,0,0]
dist = 0.0
for n in range(len(vIds)-1):
  v0 = vIds[n]
  v1 = vIds[n+1]

  dijkstra = vtk.vtkDijkstraGraphGeodesicPath()
  dijkstra.SetInputConnection(cylinder.GetOutputPort())
  dijkstra.SetStartVertex(v0)
  dijkstra.SetEndVertex(v1)
  dijkstra.Update()

  pts = dijkstra.GetOutput().GetPoints()
  for ptId in range(pts.GetNumberOfPoints()-1):
    pts.GetPoint(ptId, p0)
    pts.GetPoint(ptId+1, p1)
    print(math.sqrt(vtk.vtkMath.Distance2BetweenPoints(p0, p1)))
    dist += math.sqrt(vtk.vtkMath.Distance2BetweenPoints(p0, p1))

  appendFilter.AddInputData(dijkstra.GetOutput())

print(dist)

appendFilter.Update()

Hello, thank you for your answer.
I tried what you said but I'm having difficulties implementing it. I'm
setting the values of the actor using vtkLookupTable but the scalar bar is
not displayed.
I followed the code and it fails
in vtkContext2DScalarBarActor::PaintColorBar because it fails the casting
of the LookupTable from vtkLookupTable to
vtkDiscretizableColorTransferFunction (and it is normal, as they are in
different parts of the inheritance tree).

Then, I tried to define the LookupTable as
vtkDiscretizableColorTransferFunction, but I can't find the way to make it
work.
First of all, I would like to define the first and last value, and map
between them using a given number of values (see call
SetNumberOfTableValues). In vtkLookupTable I do this by setting the HSV
range. I guess I could do the same calling
vtkDiscretizableColorTransferFunction::AddHSVPoint(). But the colors in
between are not correct.
Second thing is that the range is wrong and the method
vtkScalarsToColors::SetTableRange is not available in
vtkDiscretizableColorTransferFunction. See in the screenshot how the values
go from 0 to 1 instead of from 293 to 630...

Here's the code of how I do it with vtkLookupTable:
vtkSmartPointer<vtkLookupTable> tempLUT =
vtkSmartPointer<vtkLookupTable>::New();
tempLUT->SetRampToLinear();
tempLUT->SetTableRange (rangeForTable);
tempLUT->SetNumberOfTableValues(m_configuration.numOfColors);
tempLUT->SetHueRange (m_configuration.rangeHue[0],
m_configuration.rangeHue[1]);
tempLUT->SetSaturationRange (m_configuration.rangeSaturation[0],
m_configuration.rangeSaturation[1]);
tempLUT->SetValueRange (m_configuration.rangeValue[0],
m_configuration.rangeValue[1]);
tempLUT->Build();

Here's my code with vtkDiscretizableColorTransferFunction, which doesn't
work (see screenshot):
vtkSmartPointer<vtkDiscretizableColorTransferFunction> tempLUT =
vtkSmartPointer<vtkDiscretizableColorTransferFunction>::New();
tempLUT->AddHSVPoint(0, m_configuration.rangeHue[0],
m_configuration.rangeSaturation[0], m_configuration.rangeValue[0]);
tempLUT->AddHSVPoint(1, m_configuration.rangeHue[1],
m_configuration.rangeSaturation[1], m_configuration.rangeValue[1]);
tempLUT->SetNumberOfValues(m_configuration.numOfColors);
tempLUT->SetIndexedLookup(0);
tempLUT->Build();

I attach a screenshot of the difference I get.

Thank you!

Subject: [vtkusers] Support for scout lines on DICOM images
Message-ID: <1507885964528-0.post@n5.nabble.com>

Hi, 


I am new to VTK.I have some doubts regarding localizer planning or Drawing
scout lines on Dicom image. 


Does VTK provide any support for drawing scout lines on DICOM image? or what
are the functions VTK provides to synchronize lines(draw corresponding lines
on other planes) on localizer images? 

Note: Localizer images are low resolution images comprising 3 orthogonal
planes (axial, coronal, and sagittal) that cover most of the anatomical
area. 


Thanks

Subject: [vtkusers] QVTKWidget in QT GUI freezes other QWidgets
Message-ID: <1853915668.12432281507888815273.JavaMail.httpd@fep-webmail-05>

Hello everyone!

I have a problem with the QT GUI I am creating. Basically, I have an interactive QWidget, a QVTKWidget and a "Quit" button. 

When I launch my app, I can interact with the QWidget without any problem (I have a 3D interactive scene, where I can zoom and rotate). 
However, as soon as the QVTKWidget becomes "active" (i.e. some function in my code start using it or if I click on it), both the QWidget and the QVTKWidget freeze. The app keeps on working, since the "Quit" button works as it should.

If I have a GUI with either the QWidget or the QVTKWidget (only one of them) everything works fine. The problem is if I try to include both of them at the same time.

Do you have any idea why this happens? 
Thanks a lot for you help.

By default the vtkDiscretizableColorTransferFunction interpolates colors
through the RGB color space. To replicate what the vtkLookupTable does, you
will need to call

tempLUT->SetColorSpaceToHSV();

tempLUT->SetRange(min, max); should do the trick.

Subject: [vtkusers] VTK openVR Controller Settings
Message-ID: <59e1a9ef.5037630a.e5ec5.a283@mx.google.com>

Hi Everyone,

Can someone please show me how to turn on ray for htc vive controllers ?

I know I need to use ShowRay function of vtkOpenVRInteractorStyle:- 
https://www.vtk.org/doc/nightly/html/classvtkOpenVRInteractorStyle.html

But I am unable to pass the proper argument and I get an exception
What I have tried doing:-

vtkEventDataDevice controller = vtkEventDataDevice::RightController;
style->ShowRay(controller);

But it doesn?t work ?

Can someone please help!

Thanks in advance.

Hello.
By default, the vtk object is drawn in the center of the screen.
It is necessary to shift the coordinates (0,0,0) to the lower left corner of
the screen, so that the figure is located there.
Thank you!

Can I somehow build something like this?
The movement of the object and the line of its movement.
As in the video below:

Dear Dan,

In QtCreator I added a QWidget to the UI form and used "Promote to ..." 
QVTKOpenGLWidget class for it. I also included QVTKOpenGLWidget.h in the 
header file of the application. However, when linking the source I get 
the error message

distortionpage.obj:-1: Fehler: LNK2019: unresolved external symbol 
"__declspec(dllimport) public: __thiscall 
QVTKOpenGLWidget::QVTKOpenGLWidget(class QWidget *,class QFlags<enum 
Qt::WindowType>)" 
(__imp_??0QVTKOpenGLWidget@@QAE at PAVQWidget@@V?$QFlags at W4WindowType@Qt@@@@@Z) 
referenced in function "public: void __thiscall 
Ui_DistortionPage::setupUi(class QWidget *)" 
(?setupUi at Ui_DistortionPage@@QAEXPAVQWidget@@@Z)


It seems that the MSVC2013 linker cannot find the library of 
QVTKOpenGLWidget. I searched a library file with a similar name in the 
folder where CMake generated the VTK libraries with Qt support but I 
could not find it. I am just wondering if it is missing or some other 
library file with a completely different name contains this symbol.

Regards,
Zoltan

The class is part of the vtkGUISupportQt library (on Windows the files
would be vtkGUISupportQt-8.0.lib/dll).

We're using the "promote" functionality in Qt Creator's Design mode to
promote a widget to our custom QVTKOpenGLWidget subclass. It should
work fine to promote to it directly.

Dear Elvis,

Thanks for the information. I have the files
-lvtkGUISupportQt-8.0 \
-lvtkGUISupportQtSQL-8.0 \
in the library list and the libary path is also given in the project 
file loaded in QtCreator but the compiler cannot resolve the symbol 
QVTKOpenGLWidget:

It seems that the compiler switches contain the include path for VTK but 
the library path and the libraries for VTK are missing from the linker 
options. I guess it must be a qmake issue. Thanks anyway.

Regards,
Zoltan

I think in order to shorten the linker command line and not exceed
command line length limits, qmake is using a "Linker Response File"
(using @), so I think you have to look into

    C:\Users\zko\AppData\Local\Temp\AM_GUI.exe.8900.4259.jom

to see the full list of linker arguments.

Would be interesting to see the contents of that file.

I just realized that it's probably temporary and removed by the time
the command finishes. But you can add /U to the jom options to have
the contents printed when the linker runs.

E.g. in Qt Creator, under Projects -> Build & Run -> Build -> Build
Steps, add /U to the jom options in the make step.

Then you should get the contents of the linker response file printed
while building.

In the project settings I set from Debug version to Release version and 
I can link the porject now. It seems that the VTK Relase libaries cannot 
be used with Debug version of the QtCreator project. I was not careful 
enough when I tried to buil the debug version of the Qt app. Thanks a 
lot for the linker output info!

Ah, glad to hear it. I started experimenting myself in a Windows VM,
and came up with this .pro file for my minimal test (the cone example
adapted to use a QVTKOpenGLWidget promoted from QWidget in the Design
mode):

CONFIG += c++11
QT += core gui widgets
TARGET = VTKQtQMakeTest
TEMPLATE = app
SOURCES += main.cpp mainwindow.cpp
HEADERS += mainwindow.h
FORMS += mainwindow.ui

INCLUDEPATH += C:/Users/Elvis/Dev/VTK-8.0.1-inst/include/vtk-8.0
DEFINES += vtkRenderingCore_AUTOINIT=$$shell_quote(2(vtkInteractionStyle,vtkRenderingOpenGL2))
LIBS += -L"C:/Users/Elvis/Dev/VTK-8.0.1-inst/lib"
LIBS += -lvtkCommonCore-8.0 \
        -lvtkCommonDataModel-8.0 \
        -lvtkCommonExecutionModel-8.0 \
        -lvtkCommonMath-8.0 \
        -lvtkCommonMisc-8.0 \
        -lvtkCommonTransforms-8.0 \
        -lvtkFiltersCore-8.0 \
        -lvtkFiltersSources-8.0 \
        -lvtkGUISupportQt-8.0 \
        -lvtkInteractionStyle-8.0 \
        -lvtkRenderingCore-8.0 \
        -lvtkRenderingOpenGL2-8.0

I think when using QMake, you will have to mess about with the
initialization of implementation modules [1] in order for the program
to run, either by using DEFINES like I did above, or using
VTK_MODULE_INIT. This is something you can get "for free" when using
CMake.

I could never run my test app, since the VM (VirtualBox) doesn't have
a sufficient OpenGL implementation. But it compiled and linked at
least.

Another tip if you're going to stick to using QMake is the
Utilities/Maintenance/WhatModulesVTK.py Python script in VTK sources,
which you can run on your source to find out which VTK modules (and
thus libraries) you're using.

Example (on Linux):

[estan at newton orexplore]$ VTK/Utilities/Maintenance/WhatModulesVTK.py
VTK ~/VTKQtQMakeTest
Modules and their dependencies:
find_package(VTK COMPONENTS
  vtkCommonCore
  vtkCommonDataModel
  vtkCommonExecutionModel
  vtkCommonMath
  vtkCommonMisc
  vtkCommonTransforms
  vtkFiltersCore
  vtkFiltersSources
  vtkGUISupportQt
  vtkRenderingCore
  vtkRenderingOpenGL2
  vtkkwiml
)
Your application code includes 12 of 204 vtk modules.

All modules referenced in the files:
find_package(VTK COMPONENTS
  vtkCommonCore
  vtkFiltersSources
  vtkGUISupportQt
  vtkRenderingCore
  vtkRenderingOpenGL2
)
Your application code includes 5 of 204 vtk modules.

Minimal set of modules:
find_package(VTK COMPONENTS
  vtkFiltersSources
  vtkGUISupportQt
)
Your application code includes 2 of 204 vtk modules.


[estan at newton orexplore]$

The first list ("Modules and their dependencies") is what you'd need
to use when using QMake.

The script is not perfect (but helps a lot), and you'll have to modify
the script slightly like this to tell it you're using the OpenGL2
backend:

diff --git a/Utilities/Maintenance/WhatModulesVTK.py
b/Utilities/Maintenance/WhatModulesVTK.py
index 9e667f0..8d8ec87 100755

Thanks for the detailed information! It is very useful, especially the 
line

DEFINES += 
vtkRenderingCore_AUTOINIT=$$shell_quote(2(vtkInteractionStyle,vtkRenderingOpenGL2)) 


I inserted it into my project file but I get the error "no override 
found for 'vtkPolyDataMapper'". I guess I must include other switches in 
the shell_quote argument too, such as vtkRenderingVolumeOpenGL or 
something else.

Hm, I'm not sure, but think that should have been taken care of by the
vtkRenderingOpenGL2. I may have messed something up with the QMake
syntax, so it would be interesting to see the actual compile line for
one of your sources (again with /U I think), to see what the /D-flag
ended up looking like.

(Note: Everything is definitely much easier with CMake, and I would
highly recommend taking the time switching to it. We use it for our
VTK+Qt project and it works just fine. We also use Qt Creator as the
primary IDE, and it can open CMakeLists.txt.)

I have the line
-lvtkRenderingOpenGL2-8.0 \
in the library list of the project file and the corresponding library 
file is also in the lib folder of the installed VTK. I can try to 
include the header vtkAutoinit.h and add these variables with the macro 
VTK_MODULE_INIT. It may work.

Yes, it may be more reliable to use the VTK_MODULE_INIT macro perhaps,
but I think it should work with the *_AUTOINIT defines as well.

Just remember when using VTK_MODULE_INIT to do everything before you
include the first VTK header.

I had a look at my compile output on Windows when using

    DEFINES += vtkRenderingCore_AUTOINIT=$$shell_quote(2(vtkInteractionStyle,vtkRenderingOpenGL2))

and it had

    -DvtkRenderingCore_AUTOINIT="2(vtk^CteractionStyle,vtkRenderingOpenGL2)"

which I think is correct.

But yes, if you're doing volume rendering, you would also need:

    DEFINES += vtkRenderingVolume_AUTOINIT=$$shell_quote(1(vtkRenderingVolumeOpenGL2))

But I don't think you would have gotten "no override found for
'vtkPolyDataMapper'" from missing that.. I think that error would be
indicative of a missing vtkRenderingOpenGL2 initialization (not sure
though..).

Actually, the macro VTK_MODULE_INIT worked. I have only the issues now like

ERROR: In 
C:\VTK\VTK-8.0.1\VTK-8.0.1\Rendering\OpenGL2\vtkWin32OpenGLRenderWindow.cxx, 
line 701
vtkWin32OpenGLRenderWindow (050E8798): We have determined that your 
graphics system is an Intel SandyBridge based system. These systems only 
partially  support VTK. If you encounter any issues please make sure 
your graphics drivers from Intel are up to date.

ERROR: In C:\VTK\VTK-8.0.1\VTK-8.0.1\GUISupport\Qt\QVTKInteractor.cxx, 
line 147
QVTKInteractor (04FF6098): QVTKInteractor cannot control the event loop.

The first ERROR is just because of the partially support of Intel 
SandyBridge by VTK. That is OK  :-) .
The second one is due to my limited knowledge on the usage of 
vtkInteractor with QVTKWidget. But it is not a technical issue. I just 
have to find out the correct usage.

Since I want to open an STL file by VTK in a Qt window I do not need the 
volume rendering now. It works now with an STL file:  the polgon surface 
appears QtVTKWidget  window and I can rotate it with mouse even if I had 
an error with the QVTKInteractor.

Of course, you are right. It would be definetely easier to use CMake 
with VTK and I would gladly migrate from qmake to cmake. Unfortunately 
the development project here uses qmake for the application handling STL 
files.
However, it seems to work now. Thanks a lot!

Hello everyone!

I have a problem with the QT GUI I am creating. Basically, I have an
interactive QWidget, a QVTKWidget and a "Quit" button.

When I launch my app, I can interact with the QWidget without any problem
(I have a 3D interactive scene, where I can zoom and rotate).
However, as soon as the QVTKWidget becomes "active" (i.e. some function in
my code start using it or if I click on it), both the QWidget and the
QVTKWidget freeze. The app keeps on working, since the "Quit" button works
as it should.

If I have a GUI with either the QWidget or the QVTKWidget (only one of
them) everything works fine. The problem is if I try to include both of
them at the same time.

Do you have any idea why this happens?


I don't have any immediate ideas. It would really help to see a small
example where the problem occurs.

Does it work if you put two of your QWidgets in the application. I mean, if
you remove the QVTKWidget and put another one of your QWidget where it was?

Elvis


Thanks a lot for you help.

Hello Elvis,
thanks for your reply. 
I don't have the gui avaiable right now; I will send a picture as soon as I can.
To answer your question: yes, if I remove the QVTKWidget and replace it with QWidget everything works. The problems occur only when the QVTKWidget is present. 

The GUI is built to work in this way:1) start showing stuff on the QWidget;2) After a while, the QVTKWidget shows some other stuff.
The QWidget is showing some interactive scene and it uses a library ("librviz" - for ROS users) based on Ogre and OpenGL. Could the problem happen because the QVTKWidget interfere with the already existing OpenGL context? 
I don't know if this is the cause, because it is sufficient to have the QVTKWidget on the Gui to make the QWidget freeze.

Anyway, I have looked at this example: https://www.vtk.org/Wiki/VTK/Examples/Cxx/GLUTbut no luck so far. Maybe is a problem of drivers (I have an Nvidia GeForce GTX 950M on Ubuntu 14.04 LTS). 

Best,Luca

I don't know, but it sounds like it's possible. I think there are
other people on this list who knows much more about OpenGL and how VTK
uses it than I do, so I'll let those answer that.

Hi VTK user,

I open several VTK renderers, display meshes with texture with integrated

Message-ID: <CADfmk-RR3vbfwvObLYA=tF5FF294wN4+srvDNQ+py2-2r52yUg@mail.gmail.com>

Hello,



I?m trying to compile VTK 8.0.1 with AcceleratorsVTKm with CUDA and TBB
enabled. I?ve tried the vtkm-1.0.0 release, the master branch from the vtkm
git repo and commit:



commit 1f451d538bf9a7beec0f443775f79c9348f9a376

Merge: 3a8a64df 33afb076

Author: Robert Maynard <robert.maynard at kitware.com>

Date:   Fri Aug 11 12:23:14 2017 +0000



that was the last one with ResultField in vtkm::filter



None of them worked, the last one was the one that took me further, but
vtkmGradient.cu will fail complaining about
vtkm::cont::vtkmCellSetExplicitAOS and vtkm::cont::vtkmCellSetSingleType
missing GetNumIndicesArray.



What is the recommended version of vtkm to compile VTK-8.0.1?



Thanks,

Hi Luca,

   -

   Do the QWidget and QVTKWidget overlap at all or are they separated by

Subject: [vtkusers] Histogram between two points on DICOM image
Message-ID: <1508245981107-0.post@n5.nabble.com>

Hi,

I want to create histogram plot between 2 points in dicom image.
But I am newer of VTK so I don't know how i do this.

I don't know these things.

1. specify two points as coordinate
2. get pixel values on the line
3. create histogram

I could read dicom image.
So please help me!

Hello Sankhesh,
thanks a lot for the reply.
Let's say the GUI "pipeline" is as I explained to Elvis. Then:
At the moment the two widgets are under the central widget (a QWidget). They are in two different tabs of a QTabWidget. I tried to move the QVTKWidget out of its tab but no luck. I have also noted another thing. If I show at the same time the QWidget and the QVTKWidget, the QVTKWidget works fine, but the QWidget freeze. That's why I thought that it could be an OpenGL context issue.
What do you mean by "replacing ROS widget with a simple button"? In any case, I can make QVTKWidget work, but no success with the QWidget. It just freeze on the last view.Unfortunately, QVTKOpenGLWidget is available only for VTK 8.0 and higher. I am using VTK 7.1 and I cannot upgrade to 8.0 because of the cmake that is installed on my laptop. I cannot upgrade the cmake version due to some compatibility issues with ROS. I will get in a lot of trouble if I try to do that. Is there a way to use glut or vtkOpenGLRenderer (available in vtk 7.1)?Thanks a lot again for the help.
Best,
Luca

Hi Luca,

Do the QWidget and QVTKWidget overlap at all or are they separated by some QFrame border, etc. ? If they are not overlapping, it means they are not sharing the OpenGL context.

Have you tried replacing the ROS widget with a simple button to see if the QVTKWidget works properly?

Lastly, the QVTKWidget is known to have rendering issues with Qt5. Try using the QVTKOpenGLWidget to see if anything changes.

I don't know, but it sounds like it's possible. I think there are

other people on this list who knows much more about OpenGL and how VTK

uses it than I do, so I'll let those answer that.

How are you initializing the QVTKWidget?
One other thing to test would be to try removing the QTabWidget and showing
both the QVTKWidget and QWidget in the same central widget side-by-side.
Finally, you could see if the setup works fine with Qt4.

I am not sure how you would put a GLUT window inside a QWidget. But if you
have can do that, you could try the vtkExternalOpenGLRenderWindow. See
TestGLUTRenderWindow.cxx
<https://gitlab.kitware.com/vtk/vtk/blob/e029e1634631893147fad2c6b379b6ff7db92881/Rendering/External/Testing/Cxx/TestGLUTRenderWindow.cxx>
for an example.

When one of the projects I work on first started using Qt5 with VTK we had
similar problems.  Embedding a QVTKWidget in a Qt5 Tab or Scroll widget or
using it alongside other OpenGL-based widgets in Qt5 can cause these kinds
of issues and this was the motivation for creating the QVTKOpenGLWidget.
The QVTKOpenGLWidget correctly lets Qt manage the OpenGL context rather
than hacking it in with window system calls.  You could try grabbing the
QVTKOpenGLWidget code from VTK 8.0.0 and copying it into your project as a
temporary solution (I'm not sure if it relies on any features added between
7.1 and 8.0).

You said upgrading CMake was blocking you from using more recent VTK?  The
CMake developers try really hard to be backwards compatible.  Have you
reported the issues you are having to them?  I know they try their best to
handle compatibility issues that are reported.

HTH,
Shawn

Thanks a lot Yoshimi.
However there is a problem of attibute in the script:

 ??? appendFilter.AddInputData(dijkstra.GetOutputPort())
AttributeError: AddInputData

Does the script works for you?
Best,

Frederic

Thanks to everyone for the inputs.
I will try to include the QVTKOpenGLWidget in my project. I will let you know if I succeed in doing that and if this solve the issue.
@Shawn -> About the Cmake: I can successfully build VTK 8.0 and use it in QT if I use a newer version of cmake (currently, the default cmake version for my system is 3.2.2). The problem is that I cannot build my project with VTK 8.0 using ROS. So the problem is not Cmake itself, but the version ROS uses for building (too "old" for VTK 8.0). I will try also to fix this.
For the moment, thanks to all. I will let you know in case of success/failure.
Best,Luca

Ogg: Re: [vtkusers] QVTKWidget in QT GUI freezes other QWidgets



When one of the projects I work on first started using Qt5 with VTK we had similar problems.  Embedding a QVTKWidget in a Qt5 Tab or Scroll widget or using it alongside other OpenGL-based widgets in Qt5 can cause these kinds of issues and this was the motivation for creating the QVTKOpenGLWidget.  The QVTKOpenGLWidget correctly lets Qt manage the OpenGL context rather than hacking it in with window system calls.  You could try grabbing the QVTKOpenGLWidget code from VTK 8.0.0 and copying it into your project as a temporary solution (I'm not sure if it relies on any features added between 7.1 and 8.0).

You said upgrading CMake was blocking you from using more recent VTK?  The CMake developers try really hard to be backwards compatible.  Have you reported the issues you are having to them?  I know they try their best to handle compatibility issues that are reported.

HTH,
Shawn

How are you initializing the QVTKWidget?
One other thing to test would be to try removing the QTabWidget and showing both the QVTKWidget and QWidget in the same central widget side-by-side. Finally, you could see if the setup works fine with Qt4.
I am not sure how you would put a GLUT window inside a QWidget. But if you have can do that, you could try the vtkExternalOpenGLRenderWindow. See TestGLUTRenderWindow.cxx for an example.

Hello Sankhesh,
thanks a lot for the reply.
Let's say the GUI "pipeline" is as I explained to Elvis. Then:
At the moment the two widgets are under the central widget (a QWidget). They are in two different tabs of a QTabWidget. I tried to move the QVTKWidget out of its tab but no luck. I have also noted another thing. If I show at the same time the QWidget and the QVTKWidget, the QVTKWidget works fine, but the QWidget freeze. That's why I thought that it could be an OpenGL context issue.
What do you mean by "replacing ROS widget with a simple button"? In any case, I can make QVTKWidget work, but no success with the QWidget. It just freeze on the last view.Unfortunately, QVTKOpenGLWidget is available only for VTK 8.0 and higher. I am using VTK 7.1 and I cannot upgrade to 8.0 because of the cmake that is installed on my laptop. I cannot upgrade the cmake version due to some compatibility issues with ROS. I will get in a lot of trouble if I try to do that. Is there a way to use glut or vtkOpenGLRenderer (available in vtk 7.1)?Thanks a lot again for the help.
Best,
Luca

Hi Luca,

Do the QWidget and QVTKWidget overlap at all or are they separated by some QFrame border, etc. ? If they are not overlapping, it means they are not sharing the OpenGL context.

Have you tried replacing the ROS widget with a simple button to see if the QVTKWidget works properly?

Lastly, the QVTKWidget is known to have rendering issues with Qt5. Try using the QVTKOpenGLWidget to see if anything changes.


Best,
Sankhesh

I don't know, but it sounds like it's possible. I think there are

other people on this list who knows much more about OpenGL and how VTK

uses it than I do, so I'll let those answer that.

Subject: [vtkusers] how to handle an empty pipeline?
Message-ID: <5EF295C7-E9E3-4BE9-930D-1ED2FA7B910E@contoso.com>

Hi --

What's the right way to handle a pipeline that might at times have no data in it?   I'm connecting to a vtkDataSetMapper,  and if the input stream is empty vtk prints a warning "vtkDataSetSurfaceFilter: Number of cells is zero, no data to process".    I don't create the vtkDataSetSurfaceFilter myself -- it's been inserted into the pipeline by the mapper.  It doesn't do that if the input data is poly data, and if I change the input to poly data, the mapper seems quite happy with the empty pipeline, so it's odd that it complains in one case but not the other.

Is there something that I should do at the pipeline source to tell the pipeline not to run?  Is there a way to suppress just this one warning message?

I'm using vtk 7.1.1 in C++.

Thanks.

Luca, 

I haven't looked into your problem/thread in detail, but I have one suggestion that might come useful: are you maybe at some point doing things in a secondary thread, and somehow passing data to your widget from this thread?

It has happened to me in the past, and the GUI would temporarily switch to drawing in black or not updating any more.

If you are using background threads, look into this.

Best,

Alessandro

I have also noted another thing. If I show at the same time the QWidget and the QVTKWidget, the QVTKWidget works fine, but the QWidget freeze. That's why I thought that it could be an OpenGL context issue.

I cannot upgrade the cmake version due to some compatibility issues with ROS. I will get in a lot of trouble if I try to do that. Is there a way to use glut or vtkOpenGLRenderer (available in vtk 7.1)?

Hello, sorry for coming back to this topic, but I have found some cases
where this doesn't work.

I attached a screenshot.
On top is the 3d mesh cut by a plane parallel to the screen. We can see
that are some elements (hexahedrons) that got cut and they were split in
sets of tetrahedrons.
At the bottom, we see the result of calling vtkCutter ->
vtkCleanUnstructuredGrid -> vtkXMLUnstructuredGridWriter. The result are
all quads and all the generated nodes by the cut are gone, and we see no
triangles.
I would expect to have the same result that we see on the top, but with 2d
elements instead of 3d.

Here's my code:

void cutModel(vtkSmartPointer<vtkUnstructuredGrid> model, double normal[3])
{
vtkSmartPointer<vtkPlane> plane = vtkSmartPointer<vtkPlane>::New();
plane->SetOrigin(0.0, 0.0, 0.0);
plane->SetNormal(normal);

vtkSmartPointer<vtkCutter> cutter = vtkSmartPointer<vtkCutter>::New();
cutter->SetCutFunction(plane);
cutter->SetInputData(model);
cutter->GenerateTrianglesOff();
cutter->Update();

vtkSmartPointer<vtkCleanUnstructuredGrid> cleaner =
vtkSmartPointer<vtkCleanUnstructuredGrid>::New();
cleaner->SetInputConnection(cutter->GetOutputPort());
cleaner->Update();
vtkSmartPointer<vtkXMLUnstructuredGridWriter> writer =
vtkSmartPointer<vtkXMLUnstructuredGridWriter>::New();
writer->SetFileName("planecut.vtu");
writer->SetInputConnection(cleaner->GetOutputPort());
writer->SetDataModeToAscii();
writer->Write();
}



Thank you.

Thanks for the suggestion, but it won't work in this case.  The warning messages come from a vtkDataSetSurfaceFilter that's created as a protected member of the vtkDataSetMapper class, so I can't call vtkDataSetSurfaceFilter::AddObserver.   Subclassing vtkDatatSetMapper and overriding Render to get access to the filter would work, but feels wrong?

Is this a bug?  A warning is raised when the input to the vtkDataSetMapper is empty, except when the input type is VTK_POLY_DATA.

I'm connecting to a vtkDataSetMapper,  and if the input stream is empty vtk prints a warning "vtkDataSetSurfaceFilter: Number of cells is zero, no data to process".    I don't create the vtkDataSetSurfaceFilter myself -- it's been inserted into the pipeline by the mapper.  It doesn't do that if the input data is poly data, and if I change the input to poly data, the mapper seems quite happy with the empty pipeline, so it's odd that it complains in one case but not the other.

I don't know if it's good practice, but when there is no input data I usually do either of the followings:
- hide the actor so that no pipeline updates are requested by the renderer
- detach the data processing pipeline from the visualization pipeline (SetInputData(NULL))
- add a dummy data set (such as polydata with a single point) as input

I would be interested if there is a particular method recommended by VTK core developers.

Subject: Re: [vtkusers] how to handle an empty pipeline?

Thanks for the suggestion, but it won't work in this case.  The warning messages come from a vtkDataSetSurfaceFilter that's created as a protected member of the vtkDataSetMapper class, so I can't call vtkDataSetSurfaceFilter::AddObserver.   Subclassing vtkDatatSetMapper and overriding Render to get access to the filter would work, but feels wrong?

Is this a bug?  A warning is raised when the input to the vtkDataSetMapper is empty, except when the input type is VTK_POLY_DATA.

I'm connecting to a vtkDataSetMapper,  and if the input stream is empty vtk prints a warning "vtkDataSetSurfaceFilter: Number of cells is zero, no data to process".    I don't create the vtkDataSetSurfaceFilter myself -- it's been inserted into the pipeline by the mapper.  It doesn't do that if the input data is poly data, and if I change the input to poly data, the mapper seems quite happy with the empty pipeline, so it's odd that it complains in one case but not the other.

What do you do if you don't know that the pipeline will be empty?  There might be a filter that doesn't pass any of the data, but the data source and the controlling code can't know that until the pipeline executes.

When the input is modified I call Update() on the filter and check the output to see if the result is empty.

What do you do if you don't know that the pipeline will be empty?  There might be a filter that doesn't pass any of the data, but the data source and the controlling code can't know that until the pipeline executes.

    Thanks for the suggestion, but it won't work in this case.  The warning messages come from a vtkDataSetSurfaceFilter that's created as a protected member of the vtkDataSetMapper class, so I can't call vtkDataSetSurfaceFilter::AddObserver.   Subclassing vtkDatatSetMapper and overriding Render to get access to the filter would work, but feels wrong?

I'm connecting to a vtkDataSetMapper,  and if the input stream is empty vtk prints a warning "vtkDataSetSurfaceFilter: Number of cells is zero, no data to process".    I don't create the vtkDataSetSurfaceFilter myself -- it's been inserted into the pipeline by the mapper.

Ok, thanks.  I'll see how difficult that'll be in my case. 
The simple solution would be to just delete one line from vtkDataSetSurfaceFilter, but that'll make it harder to distribute my code.

Hi Steve,

In VTK 5.10, I use vtkDataSetSurfaceFilter2 which is identical to 
vtkDataSetSurfaceFilter except for the following lines in RequestData() 
which deal with the case of no cells to ensure the output is correctly 
formed ...

 ? if (numCells == 0)
 ??? {
 ??? output->CopyStructure( input );
 ??? output->GetPointData()->PassData( input->GetPointData() );
 ??? output->GetCellData()->PassData( input->GetCellData() );
 ??? return 1;
 ??? }

I have found some filters handle the case of no cells gracefully, others 
bail out too soon leaving malformed output.

You could use vtkDataSetSurfaceFilter2 before the input to 
vtkDataSetMapper in your pipeline which would send polydata into the mapper.

HTH,

John.

The warning messages come from a vtkDataSetSurfaceFilter that's created as a protected member of the vtkDataSetMapper class, so I can't call vtkDataSetSurfaceFilter::AddObserver.   Subclassing vtkDatatSetMapper and overriding Render to get access to the filter would work, but feels wrong?

I'm connecting to a vtkDataSetMapper,  and if the input stream is empty vtk prints a warning "vtkDataSetSurfaceFilter: Number of cells is zero, no data to process".    I don't create the vtkDataSetSurfaceFilter myself -- it's been inserted into the pipeline by the mapper.  It doesn't do that if the input data is poly data, and if I change the input to poly data, the mapper seems quite happy with the empty pipeline, so it's odd that it complains in one case but not the other.

occurred in OpenGL. Can we have a way catch it?

Subject: [vtkusers] Dynamically Add and Render Points using vtkPolyData
Message-ID: <1508391026744-0.post@n5.nabble.com>

Hi All, 

This will be my first post, I am new to VTK so I apologize for any Noobie
mistakes. 

Outline: Our project uses a 2D lidar on a Robot to profile areas as it
moves, we are currently using VTK to visualize these point clouds. 

The application needs to be real time as such we receive 10 scans a second
with roughly 360 points per scan. 

What is the best way to add points to PolyData and render it? 

The current method adds these points to the Polydata via: 
//Setup 
lidar_points = gcnew vtkPoints(); 
lidar_points_colors = gcnew vtkUnsignedCharArray(); 
lidar_points_colors->SetName("LidarPointsColors"); 
lidar_points_colors->SetNumberOfComponents(3); 
lidar_points_data->GetPointData()->SetScalars(lidar_points_colors); 
vertices = gcnew vtkCellArray(); 
lidar_points_data->SetPoints(lidar_points); 
lidar_points_data->SetVerts(vertices); 
lidar_points_data->GetPointData()->SetScalars(lidar_points_colors); 
lidar_points_mapper->ImmediateModeRenderingOn();


//Per scan 
for (point p in scan) 
{ 
   vtkPointData^ newPoint = vtkPointData::New(); 
   int Id = lidar_points->InsertNextPoint(new_lidar_point_x,
new_lidar_point_y, new_lidar_point_z); 
   vertices->InsertNextCell(1); 
   vertices->InsertCellPoint(Id); 
} 
lidar_points->Modified(); 
lidar_points_data->Modified(); 
lidar_points_data->Update(); 

lidar_render_window->Render(); 

I have checked and the Insert for each scan takes 3ms regardless of total
point size of PolyData. 
But the Render(); method starts at 4-5ms for an empty set and quickly grows
to 150ms for 1 million points. which already slows down the 10Hz scan rate. 

Interestingly when the scans stop, using the mouse to interact with the
scene gives a very good FPS even when there are 3 Million points 

The system has a GPU and I can verify the render calls do use the GPU, using
the mouse with 3 Million points maxes the GPU (100% utilization). 

While Points are added and rendered both the GPU and CPU of the system are
below 50%, I have tried using threads to Split adding points from the render
event but Vtk really didnt enjoy that :P 

Any Feed back would be very helpful

Hello,

Firstly the cutting algorithms are different between
vtkTableBasedClipDataSet and vtkCutter, thus in general the generated
cross sections are quite different.

I have no idea how to extract a section surface directly from output
of vtkTableBasedClipDataSet, however here are two insufficient ways:
1) vtkTableBasedClipDataSet -> vtkCutter (Cutter.tar.gz)
2) vtkTableBasedClipDataSet -> vtkGeometryFilter -> vtkPolyDataNormals
-> vtkConnectivityFilter (Cutter2.tar.gz)

1) This method conducts double cutting using the same plane in turn.
But in order to avoid the broken polygons as output of vtkCutter, the
position of a cutting plain need to be slightly shifted from the used
in vtkTableBasedClipDataSet. This means good accuracy of results are
not be retained.
2) This method divides the surface by feature edges (vtkPolyDataNormals)
and then selects the desired surface among them based on polygonal
connectivity (vtkConnectivityFilter). Here, the origin of a cutting
plane need to be known and be only on the cross section of objects so
as to extract the cross section according to the criteria "extract the
region closest to the origin". In addition, in vtkPolyDataNormals the
feature angle to determine feature edges need to be adjusted in
accordance with each dataset.

I'm sorry for my poor English.

Hi Alessandro,
at first I thought that something similar to what you describe was happening. I looked into this and double checked my code, but I think that the issue is due to OpenGL. Thanks for the hint anyway!

Luca

Luca, I haven't looked into your problem/thread in detail, but I have one suggestion that might come useful: are you maybe at some point doing things in a secondary thread, and somehow passing data to your widget from this thread?It has happened to me in the past, and the GUI would temporarily switch to drawing in black or not updating any more.If you are using background threads, look into this.Best,AlessandroOn Oct 17, 2017, at 5:23 PM, bartolomei-luca at virgilio.it wrote:Thanks to everyone for the inputs.I will try to include the QVTKOpenGLWidget in my project.

The problem is that I cannot build my project with VTK 8.0 using ROS. So the problem is not Cmake itself, but the version ROS uses for building (too "old" for VTK 8.0). I will try also to fix this.For the moment, thanks to all. I will let you know in case of success/failure.Best,Luca

Ogg: Re: [vtkusers] QVTKWidget in QT GUI freezes other QWidgets

When one of the projects I work on first started using Qt5 with VTK we had similar problems.  Embedding a QVTKWidget in a Qt5 Tab or Scroll widget or using it alongside other OpenGL-based widgets in Qt5 can cause these kinds of issues and this was the motivation for creating the QVTKOpenGLWidget.  The QVTKOpenGLWidget correctly lets Qt manage the OpenGL context rather than hacking it in with window system calls.  You could try grabbing the QVTKOpenGLWidget code from VTK 8.0.0 and copying it into your project as a temporary solution (I'm not sure if it relies on any features added between 7.1 and 8.0).You said upgrading CMake was blocking you from using more recent VTK?  The CMake developers try really hard to be backwards compatible.  Have you reported the issues you are having to them?  I know they try their best to handle compatibility issues that are reported.HTH,ShawnOn Tue, Oct 17, 2017 at 10:03 AM, Sankhesh Jhaveri <sankhesh.jhaveri at kitware.com> wrote:How are you initializing the QVTKWidget?One other thing to test would be to try removing the QTabWidget and showing both the QVTKWidget and QWidget in the same central widget side-by-side. Finally, you could see if the setup works fine with Qt4.I am not sure how you would put a GLUT window inside a QWidget. But if you have can do that, you could try the vtkExternalOpenGLRenderWindow. See TestGLUTRenderWindow.cxx for an example.

I have also noted another thing. If I show at the same time the QWidget and the QVTKWidget, the QVTKWidget works fine, but the QWidget freeze. That's why I thought that it could be an OpenGL context issue.What do you mean by "replacing ROS widget with a simple button"? In any case, I can make QVTKWidget work, but no success with the QWidget. It just freeze on the last view.Unfortunately, QVTKOpenGLWidget is available only for VTK 8.0 and higher. I am using VTK 7.1 and I cannot upgrade to 8.0 because of the cmake that is installed on my laptop. I cannot upgrade the cmake version due to some compatibility issues with ROS. I will get in a lot of trouble if I try to do that. Is there a way to use glut or vtkOpenGLRenderer (available in vtk 7.1)?Thanks a lot again for the help.Best,Luca

Hi Luca,

Do the QWidget and QVTKWidget overlap at all or are they separated by some QFrame border, etc. ? If they are not overlapping, it means they are not sharing the OpenGL context.

Have you tried replacing the ROS widget with a simple button to see if the QVTKWidget works properly?

Lastly, the QVTKWidget is known to have rendering issues with Qt5. Try using the QVTKOpenGLWidget to see if anything changes.

Best,Sankhesh

I don't know, but it sounds like it's possible. I think there are
other people on this list who knows much more about OpenGL and how VTK
uses it than I do, so I'll let those answer that.

Hello. Thank you for your answer. The method 1 worked !
I don't like method 2 because it depends a lot on the input data, which can
change... (that angle thing is a little too much for our case).
We'll use method 1 for the moment!
My problem was that the input of vtkCutter wasn't the output of
vtkTableBasedClipDataSet but the original model itself, then the mesh in
the cut got calculated twice and using different methods.

Thanks a lot!

Subject: [vtkusers] get vtkImageData point
Message-ID: <1508420326459-0.post@n5.nabble.com>

Hi,

I get the pixel value from x-y-z real-world coordinate.
For getting pixel value, by vtkImageData Class Reference, GetScalarPoint is
useful but its arguments are only int, i-j-k points of image.

So I want to convert real-world x-y-z coordinate to image i-j-k points and
get pixel value.
If there is directory converting method, please tell me.

Or
I could convert x-y-z coordinate to vtkIdType by using FindPoint method.
So, please tell me the method converting vtkIdType to image i-j-k points.

Please help!

	contous
Message-ID: <tencent_B06876281AB0F25559CF901BB95B689DF008@qq.com>

Hi,

I have get 3D display using vtkFixedPointVolumeRayCastMapper for CT dicom images. I also have several drawing contours from CT dicom images. I use vtkVoxelContoursToSurfaceFilter to get 3D display about drawing contours. I want to get 3D display together dicom image with drawing contours in the same vtkRenderer. But the 3D display of drawing contours is not in the correct position in 3D display of ct dicom images. x, y position is ok. z position is not correct. 
So what shall I do? Is there some examples to do this ?


Thank you very much!

You can use vtkImplicitVolume, it has these methods:
  void SetVolume(vtkImageData *data)  - set the data to use
  double FunctionValue(double xyz[3]) - get the data value at (x,y,z)

Or you can use vtkImageInterpolator, which is described here:
https://www.vtk.org/Wiki/VTK/Image_Interpolators

Message-ID: <CAAwbXtFRb+S+vmmYk0QGUXcpcuVzks6TwH-O+w9AqBSmF+WTwg@mail.gmail.com>

Hi, All


I have an application on hands sitting on top of VTK 5.3. Using
vtkDICOMImageReader I'm getting image position, width, height, ..., so far
so good.

But is there a good way to read ImageType string with tag (0008,0008)?

More general, could I read any tag back using vtkDICOMImageReader? Pass tag
value, get back what's in the DICOM file?

thank you


OK

Last question Yoshimi (or others),

With your script*, is-there a way to extract the point (in x,y,z or 
vertex value) where dist/2 (the half of the total geodesic distance)?

Thanks for your kindness,

Frederic

Message-ID: <CADnb_XKvOOy_Pr4kkoQs8Kn8AARE6XcVhYcGrsyeTcKphiUFfw@mail.gmail.com>

 Hi all,

I am working through some examples and trying to add my own data.

I'm running VTK-8 on ubuntu 16.04.

The original examples code adds 8 cells, the example runs fine,
my hack of the example attempts to add 49000ish cells comes out with an
error.

The following code:

    gap_data_block = get_gap_data_block()
    voxelPoints = vtk.vtkPoints()
    voxelPoints.SetNumberOfPoints(len(gap_data_block))
    voxelPoints.SetData(VN.numpy_to_vtk(gap_data_block, deep=True))

    print("len(gap_data_block))
    print(gap_data_block.shape)

    aVoxel = vtk.vtkVoxel()

    for i in range(len(gap_data_block[:, 0])):
        print(len(gap_data_block), i)
        aVoxel.GetPointIds().SetId(i, i)

Gives the following output and nasty error - what is going on here??

Output:
Length Gap Data Block: 49432
Shape Gap Data Block: (49432, 3)
0
1
2

Subject: [vtkusers] Merging an example with my data
Message-ID: <CADnb_X+BZz3+nV922o1rU4eFv1+CRDVkdKL2n4Q-cXq7m02uSQ@mail.gmail.com>

I am looking at the pointToCellData.py example.

In that example an unstructured grid reader opens a .vtk file and extracts
some named unstructured grid scalar and vector data like so...

reader = vtk.vtkUnstructuredGridReader()
reader.SetFileName(VTK_DATA_ROOT + "/Data/blow.vtk")
reader.SetScalarsName("thickness9")
reader.SetVectorsName("displacement9")

p2c = vtk.vtkPointDataToCellData()
p2c.SetInputConnection(reader.GetOutputPort())
p2c.PassPointDataOn()
warp = vtk.vtkWarpVector()
warp.SetInputConnection(p2c.GetOutputPort())
thresh = vtk.vtkThreshold()
thresh.SetInputConnection(warp.GetOutputPort())
thresh.ThresholdBetween(0.25, 0.75)
thresh.SetInputArrayToProcess(1, 0, 0, 0, "thickness9")


In the code I've written to front end this, I want to replace the reader
with my own method for extracting an unstructured grid like so...

gap_data_block, gap_file_info = getgap.get_gap_data_from_files(gap_file)
points = vtk.vtkPoints()
points.SetData(VN.numpy_to_vtk(gap_data_block, deep=True))
ugrid = vtk.vtkUnstructuredGrid()
ugrid.SetPoints(points)

Where gap_data_block is a numpy array of shape (n,3) carrying data for
dimensions are x/y/z.

Ultimately I want to get a surface elevation plot of gap_data_block by
working through the example code cited above.

As part of this (extremely) pedagogical experience, I feel I need to do two
things:

   1. Find a way to label columns one and two of get_data_block as a vector
   using some equivalent to reader.SetVectorsName()
   2. Find a way to label columns three of get_data_block as a scalar using
   some equivalent to reader.SetVectorsName()
   3. Find a way to set the input connection, or input data of a
   vtkPointDataToCellData object to my vtkUnstructuredGrid object ugrid.

I've been looking at this for a few hours now, any help getting my ugrid to
an elevation plot would be appreciated.

Thanks,

nt

Thank you Bill!

I read the document of vtkImageData::ComputeStructuredCoordinates, but I
don't know the parameters.

The definition is :
virtual int vtkImageData::ComputeStructuredCoordinates(const double x[3],
int ijk[3], double pcoords[3])

I know x is the real world x-y-z coordinate, and ijk is image point, but
what is pcoords???
pcoords is the parametric coordinates in the cell, but i don't know that.

And i thought the usage :

const double p[3] = {x, y, z}; // already know
double pcoords[3] = {?, ?, ?}; // already know
int ijk[3]; // I want know

int check = image->ComputeStructuredCoordinates(p, ijk, pcoords);
if (check == 1) {
    std::cout << "(" << ijk[0] << ", " << ijk[1] << ", " << ijk[2] << ")" <<
std::endl;
}

Is this right?

please help me!

Hello Frederic,

vtkSCurveSpline seems to be capable of calculating the coordinate at
the midpoint of the geodesic path by an interpolating spline.

import vtk
import math

cylinder= vtk.vtkSphereSource()
cylinder.SetCenter(0.0, 0.0, 0.0)
cylinder.SetRadius(0.5)

points = vtk.vtkPoints()

vIds = [4, 12, 23, 28]

p0 = [0]*3
p1 = [0]*3
dist = 0.0
for n in range(len(vIds)-1):
   v0 = vIds[n]
   v1 = vIds[n+1]

   dijkstra = vtk.vtkDijkstraGraphGeodesicPath()
   dijkstra.SetInputConnection(cylinder.GetOutputPort())
   dijkstra.SetStartVertex(v0)
   dijkstra.SetEndVertex(v1)
   dijkstra.Update()

   pts = dijkstra.GetOutput().GetPoints()
   end = n<len(vIds)-2 and 0 or -1
   for ptId in range(pts.GetNumberOfPoints()-1, end, -1):
     pts.GetPoint(ptId, p0)
     points.InsertNextPoint(p0)

   for ptId in range(pts.GetNumberOfPoints()-1):
     pts.GetPoint(ptId, p0)
     pts.GetPoint(ptId+1, p1)
     #print(math.sqrt(vtk.vtkMath.Distance2BetweenPoints(p0, p1)))
     dist += math.sqrt(vtk.vtkMath.Distance2BetweenPoints(p0, p1))

print('length: ' + str(dist))

Subject: [vtkusers] Adding Implicit Functions To Renderer?
Message-ID: <1508480380434-0.post@n5.nabble.com>

Pretty simple question. But I couldn't find anything googling. How can I add
vtkImplicitFunctions as actors. For instance, I want to add a vtkPlane as an
actor to the renderer.

Subject: [vtkusers] DICOM pixel value is strange
Message-ID: <1508483186051-0.post@n5.nabble.com>

Hi,

I wrote the code to pick the DICOM pixel value, but pixel value is strange.
My code is below:

```
vtkSmartPointer<vtkImageData> image = reader->GetOutput();

int ijk[3];
double pcoords[3];

for (vtkIdType id = 0; id < image->GetNumberOfPoints(); ++id) {
        int check = image->ComputeStructuredCoordinates(image->GetPoint(id),
ijk, pcoords);
        cout << "ID: " << id << ", ";
        cout << "ijk: " << "(" << ijk[0] << ", " << ijk[1] << ", " << ijk[2]
<< "), ";
        auto *pixel = static_cast<double*>(image->GetScalarPointer(ijk));
        cout << "Pixel: " << *pixel << endl;
}
```

I supposed *pixel value is in the range 0 ~ 255, but actual output is like
-2.06898e+289.
Why?
Moreover, *pixel max value is 1.98914e-289, and sometimes *pixel is nan.
It's strange!!!

Can you help me?

If you have found a solution, it would be nice to share it for anyone
having a similar problem in the future.

Hi Kurt,

I tried it using the following solution. Unfortunately the vtkAppendPolyData
filter in the end produces non-manifold edges as it just adds both meshes
together without combining the edges on each border. Also it is not a super
clean solution using a set for the IDs.


ids = set()

selectedPolyData = vtk.vtkPolyData()
selectedPolyData.DeepCopy(originalPolyData)
selectedPolyData.BuildLinks()

unselectedPolyData = vtk.vtkPolyData()
unselectedPolyData.DeepCopy(originalPolyData)
unselectedPolyData.BuildLinks()

for c in xrange(originalPolyData.GetNumberOfCells()):
    cell = originalPolyData.GetCell(c)
    if c in ids:
        unselectedPolyData.DeleteCell(c)
    else:
        selectedPolyData.DeleteCell(c)

selectedPolyData.RemoveDeletedCells()
unselectedPolyData.RemoveDeletedCells()

# subdivide or do whatever with selectedPolyData

append = vtk.vtkAppendPolyData()
append.AddInputData(selectedPolyData)
append.AddInputData(unselectedPolyData)
append.Update()

originalPolyData = append.GetOutput()

Subject: [vtkusers] Adding Implicit Functions To Renderer?
In-Reply-To: <1508480380434-0.post@n5.nabble.com>

If your goal is to actually view a vtkImplicitFunction, you'll first need
to give it to a vtkImplicitModeller that computes a volume with the signed
distance from the object the implicit function represents. Then you'll need
to apply a vtkContourFilter to it to extract a surface. Add this surface to
a mapper, assign the mapper to an actor, and you are done.

If your goal is to just view a plane, you can generate one with
vtkPlaneSource, connect its output to a mapper, and then assign the mapper
to an actor.

HTH,
Cory

Subject: [vtkusers] DICOM pixel value is strange
In-Reply-To: <1508483186051-0.post@n5.nabble.com>

It looks like you are casting the array pointer to a double array. Are your
values actually stored in doubles? Your expected range of [0, 255] suggests
they would actually be stored as unsigned chars, so first try to change your

static_cast<double*>(image->GetScalarPointer(ijk));

to

static_cast<unsigned char*>(image->GetScalarPointer(ijk));

Hope that helps,
Cory

Subject: [vtkusers] polyline and appendpolydata problem
Message-ID: <CAEAx3cPDq_f0rU8mXWL_TJ5hVJK7DjO7rRXhNs79stCJeAGmyg@mail.gmail.com>

hi all,

I am working on a 3D surface reconstruction problem.  Think of a 3D laser
scanner, where I have multiple sets of 3D points (1 set per laser scan
line).  I would like to visualize them as a set of polylines, 1 polyline
per scan line.

I wrote the following code to read these data from 2 files. One file is a
set of 3D points, the other is a text file indicating the number of points
per scan line.  I then create 1 polyline per scan line, and append them
together using vtkappendpolydata. I then wrote the results into a .vtk file.

However, visualizing the .vtk file suggests that the beginning of the nth
scan line is connected to the end of the (n-1)th scan line.  How do I
create a set of the disconnected polylines?

any help is very much appreciated,

My codes are as following:

#include <vtkSmartPointer.h>
#include <vtkAppendPolyData.h>
#include <vtkPoints.h>
#include <vtkPolyLine.h>
#include <vtkCellArray.h>
#include <vtkCellData.h>
#include <vtkPolyData.h>
#include <vtkPolyDataWriter.h>

int main ( int argc, char *argv[])
  {

  ifstream indexFile(argv[1]);
  ifstream pointFile(argv[2]);
  int num;
  double x, y, z;
  vtkSmartPointer< vtkAppendPolyData > append =
    vtkSmartPointer< vtkAppendPolyData >::New();

  while (indexFile >> num)
    {
    vtkSmartPointer< vtkPoints > points =
      vtkSmartPointer< vtkPoints >::New();
    vtkSmartPointer< vtkPolyLine > polyline =
      vtkSmartPointer< vtkPolyLine >::New();

    polyline->GetPointIds()->SetNumberOfIds(num);
    for (unsigned int i = 0; i < (unsigned int)num; i++)
      {
      pointFile >> x >> y >> z;
      points->InsertNextPoint(x, y, z);
      polyline->GetPointIds()->SetId(i, i);
      }

    vtkSmartPointer< vtkCellArray > cells =
      vtkSmartPointer< vtkCellArray >::New();
    cells->InsertNextCell(polyline);
    vtkSmartPointer< vtkPolyData > polyData =
      vtkSmartPointer< vtkPolyData >::New();
    polyData->SetPoints(points);
    polyData->SetLines(cells);
    polyData->Modified();

    append->AddInputData(polyData);
    append->Modified();
    }
  indexFile.close();
  pointFile.close();

  vtkSmartPointer< vtkPolyDataWriter > writer =
    vtkSmartPointer< vtkPolyDataWriter >::New();
  writer->SetFileName("test.vtk");
  writer->SetInputConnection(append->GetOutputPort());
  writer->Write();


  return (0);
  }

Thank you for your help, Cory!

I tried to do 

static_cast<unsigned char*>(image->GetScalarPointer(ijk));

but it doesn't work well.....
My dicom image's PixelRepresentation is 1, so i also tried to do

static_cast<signed char*>(image->GetScalarPointer(ijk));

but it also doesn't work well.

Why???

Hi

I tested your code with the following input files as a trial, however
the problem didn't occur.
---indexFile---
3
3
---------------
---pointFile---
0.0 0.0 0.0
0.0 1.0 0.0
0.0 2.0 0.0
1.0 0.0 0.0
1.0 1.0 0.0
1.0 2.0 0.0
---------------

I think you need to firstly check the validity of the input file format.

Thanks a lot

Subject: [vtkusers] My interactor style doesn't work
Message-ID: <1508586121400-0.post@n5.nabble.com>

Hi,

I'm trying to create my style subclass of vtkInteractorStyleImage.
I want to callback click event and mouse move event.

I referred to this example to display my dicom image, 
https://lorensen.github.io/VTKExamples/site/Cxx/IO/ReadDICOM/

and referred to this to create my style class.
https://www.vtk.org/Wiki/VTK/Examples/Cxx/Images/MarkKeypoints

DICOM image appear, but my mouse event does not work.
Following my code:

class MyStyle : public vtkInteractorStyleImage {
public:
    static MyStyle* New() {
        return nullptr;
    }
    vtkTypeMacro(MyStyle, vtkInteractorStyleImage);

    void OnLeftButtonDown() override {
        std::cout << "Left Button Clicked!" << std::endl;
        vtkInteractorStyleImage::OnLeftButtonDown();
    }

    void OnMouseMove() override {
        std::cout << "Mouse Moving!" << std::endl;
        vtkInteractorStyleImage::OnMouseMove();
    }

};


int main(int argc, char** argv) {
    // Verify input arguments
    if ( argc != 2 )
    {
        std::cout << "Usage: " << argv[0]
                  << " Filename(.img)" << std::endl;
        return EXIT_FAILURE;
    }
    std::string inputFilename = argv[1];

    vtkSmartPointer<vtkDICOMImageReader> reader =
            vtkSmartPointer<vtkDICOMImageReader>::New();
    reader->SetFileName(inputFilename.c_str());
    reader->Update();

    vtkSmartPointer<vtkImageViewer2> imageViewer =
            vtkSmartPointer<vtkImageViewer2>::New();
    imageViewer->SetInputConnection(reader->GetOutputPort());

    vtkSmartPointer<vtkRenderWindowInteractor> renderWindowInteractor =
            vtkSmartPointer<vtkRenderWindowInteractor>::New();
    vtkSmartPointer<MyStyle> style = vtkSmartPointer<MyStyle>::New();
    renderWindowInteractor->SetInteractorStyle( style );

    imageViewer->SetupInteractor(renderWindowInteractor);
    imageViewer->Render();
    imageViewer->GetRenderer()->ResetCamera();
    imageViewer->Render();

    renderWindowInteractor->Start();


    return EXIT_SUCCESS;

}


How change my code?
please help me!

Hello,

It seems to work to change as follows:

#include <vtkSmartPointer.h>
#include <vtkImageViewer2.h>
#include <vtkInteractorStyleImage.h>
#include <vtkDICOMImageReader.h>
#include <vtkObjectFactory.h>
#include <vtkRenderWindow.h>
#include <vtkRenderWindowInteractor.h>
#include <vtkRenderer.h>

class MyStyle : public vtkInteractorStyleImage {
public:
  static MyStyle* New();
  vtkTypeMacro(MyStyle, vtkInteractorStyleImage);

  void OnLeftButtonDown() override {
    std::cout << "Left Button Clicked!" << std::endl;
    vtkInteractorStyleImage::OnLeftButtonDown();
  }

  void OnMouseMove() override {
    std::cout << "Mouse Moving!" << std::endl;
    vtkInteractorStyleImage::OnMouseMove();
  }
};

vtkStandardNewMacro(MyStyle);

int main(int argc, char* argv[])
{
  // Verify input arguments
  if ( argc != 2 )
  {
    std::cout << "Usage: " << argv[0]
              << " Filename(.img)" << std::endl;
    return EXIT_FAILURE;
  }

  std::string inputFilename = argv[1];

  // Read all the DICOM files in the specified directory.
  vtkSmartPointer<vtkDICOMImageReader> reader =
    vtkSmartPointer<vtkDICOMImageReader>::New();
  reader->SetFileName(inputFilename.c_str());
  reader->Update();

  // Visualize
  vtkSmartPointer<vtkImageViewer2> imageViewer =
    vtkSmartPointer<vtkImageViewer2>::New();
  imageViewer->SetInputConnection(reader->GetOutputPort());
  vtkSmartPointer<vtkRenderWindowInteractor> renderWindowInteractor =
    vtkSmartPointer<vtkRenderWindowInteractor>::New();
  vtkSmartPointer<MyStyle> style = vtkSmartPointer<MyStyle>::New();

  imageViewer->SetupInteractor(renderWindowInteractor);
  imageViewer->Render();
  imageViewer->GetRenderer()->ResetCamera();
  imageViewer->Render();

  renderWindowInteractor->SetInteractorStyle(style);
  style->SetDefaultRenderer(imageViewer->GetRenderer());
  style->SetCurrentRenderer(imageViewer->GetRenderer());

  renderWindowInteractor->Start();

  return EXIT_SUCCESS;
}

Hope that helps you.

Subject: [vtkusers] Point Pick on vtkContextView
Message-ID: <1508673659618-0.post@n5.nabble.com>

Hi,

I want to point pick on vtkContextView by mouse moving.

Concretely, I refer to this example
https://lorensen.github.io/VTKExamples/site/Cxx/Plotting/LinePlot/

and I want to pick up x value at mouse pointer from the figure in this
example.

I think I should use vtkContextInteractorStyle and vtkPropPicker classes,
but I don't know how i should do coding.

Can you help me?
please.

Hi Sebastien,

I stored the data as vtk data and used the vtkDataConverter which seemed 
to work fine. When I run the code, every actor appears exactly at the 
right place. So I guess the information in the vtk data must be correct 
(without ever using any function like "setPosition"). Though I do not 
understand why I cannot retrieve the information of their positions in 
the code.

Here is how I read my data files, it is a function I found in the 
documentation:

function loadSegment(string, actor, renderer, i){
     const reader = vtkHttpDataSetReader.newInstance({ fetchGzip: true });
reader.setUrl(string).then(() => {
   reader.loadData().then(() => {
     renderer.resetCamera();
     renderWindow.render();
   });
});
const mapper = vtkMapper.newInstance();
mapper.setInputConnection(reader.getOutputPort());
actor.setMapper(mapper);
renderer.addActor(actor);
}

Any ideas what could be wrong?

Thank you for your help!

Message-ID: <1508760628117-0.post@n5.nabble.com>

Hi,

I have a problem with value picking from vtkChartXY popup box.
https://lorensen.github.io/VTKExamples/site/Cxx/Plotting/LinePlot/
In this example code, hovering mouse over the point, the rectangle box will
appear and it contains the x, y values at the point like this image.

<http://vtk.1045678.n5.nabble.com/file/t342066/ChartXY.png> 


I want to get these x, y values.

How should i do?

I have an unstructured Mesh (read via vtkExodusIIReader) and for a known
set of cells of that mesh I need to use a plane to clip the individual cell
(I have an origin and normal for each cell for which this needs to be done).

Can someone please point me in the correct direction to accomplish this

Thanks,

Ok the issue is related to the vtkDataConverter that does not properly
define the number of component to 3 for points.
You can edit the generated json to fix that. This will fix the getBounds()
call.

I'm going to fix the vtkDataConverter code.

Hum, looking at the code it seems that information should be properly set.

https://github.com/Kitware/vtk-js/blob/master/Utilities/DataGenerator/vtk-data-converter.py#L182

Are you using an older version?

Yeah but I can't connect vtkPlane and vtkPlaneSource for effortless updating.
I'd need to make some filter to connect the two. I was hoping there was some
easy way to connect them.

You can add an observer to your vtkPlane that listens to Modified events
and updates the vtkPlaneSource parameters with the parameters from the
vtkPlane. It's not effortless, but not too much work, either.

Subject: [vtkusers] The vtkSweptSurface patent has expired - is it/will it

Message-ID: <1508828099352-0.post@n5.nabble.com>

Hello,

I'm interested in using the functionality described in the vtkSweptSurface
class. This class was dropped around V5.4 because it was patented I believe,
however I think the patent has now expired.

Is there any way to get this back into VTK?

Thanx in advance,

Doug

Hello Doug,

The latest source I can find for this class is from VTK v4.4.2:

https://gitlab.kitware.com/vtk/vtk/blob/v4.4.2/Patented/vtkSweptSurface.h
https://gitlab.kitware.com/vtk/vtk/blob/v4.4.2/Patented/vtkSweptSurface.cxx

If the patent has expired for this class, I?d be happy to review a merge request that brings this class back into VTK.

Sincerely,
T.J.

Subject: [vtkusers] Actors disappear from render
Message-ID: <1508857292238-0.post@n5.nabble.com>

The actors from the render window disappear after rendering for few hours.
The actors disappear randomly. Memory consumption remains the same. 

The sample pseudo program:

vtkSmartPointer<CAnimateCallBack> object =
vtkSmartPointer<CAnimateCallBack>::New();
niCallBack->cvar= &cAvar;
cAvar->renderInteractor->AddObserver(vtkCommand::TimerEvent, className);
cAvar->renderInteractor->CreateRepeatingTimer(1);
cAvar->renderInteractor->Start();

// observer class - implemented the /virtual void Execute(vtkObject *caller,
unsigned long eventId, void * vtkNotUsed(callData))/ method

virtual void Execute(vtkObject *caller, unsigned long eventId, void *
vtkNotUsed(callData))
{
 UpdateActors(); // Modified() method not called on each actor
 cAvar->renderWindow->Render();
}

This process updates the render for few hours and later doesn't reneder few
parts

Any suggestions or ideas to solve this would be helpful.

Tom,

"If the patent has expired for this class, I?d be happy to review a merge
request that brings this class back into VTK."

Is a merge request something I can do?  (I'm not very familiar with vtk
processes....)

By the way - I'm ASSUMING the patent has expired since it was registered '95
or '96 and I beleiev patents have a 20 year life.

Tom,


Ahhh..... you're suggesting I do the merge and then request that it be
accepted.  

I was thinking that I could make the request and someone else would do the
integration and I could just use the method......... 

OK - I'll look into doing this. It'll be a stretch timewise, but it's a fair
proposal.

Subject: [vtkusers] vtk and gtk on macOS
Message-ID: <49FDD20F-0AFF-4475-B314-20C78E20EEA9@nist.gov>

Hi --

Is there a simple way to get vtk to work inside a gtk+2 program on macOS?   If there isn't a simple way, is there a difficult one?

I'm trying to get a program that uses gtk+2 and vtk to work with a modern version of vtk -- I'm upgrading from 5.10.1 to 7.1.1 or 8.0.1.    On Linux, the following code creates a vtk render window and a gtk widget containing it:
    vtkRenderWindow *render_win = vtkRenderWindow::New();
    GtkWidget *drawing_area = gtk_drawing_area_new();
    Display *disp = GDK_DISPLAY();
    render_win->SetDisplayId(disp);
followed eventually by
     XID wid = GDK_WINDOW_XID(drawing_area->window);
     render_win->SetWindowId(wid);
after receiving the gtk "realize" signal on the drawing_area.

On macOS, I'd like to use the Cocoa version of gtk+2 and vtkCocoaRenderWindow, but I can't figure out how to embed the render window into a gtk widget.    All the examples I've found on-line aren't really applicable. 

GtkGLExt might be applicable, but it doesn't look like it's being maintained.

An alternative would be to use X11, but native Mac OpenGL doesn't understand X11, so I tried installing mesa from macports , rebuilding vtk with VTK_USE_X instead of VTK_USE_COCOA, and linking to /opt/local/lib instead of /System/Library/Frameworks/OpenGL.framework.  Then I can use the same code as on Linux, but vtk complains about the context not supporting OpenGL 3.2, and then crashes:
  ERROR: In /Users/langer/UTIL/VTK/VTK-7.1.1/Rendering/OpenGL2/vtkTextureObject.cxx, line 440
  vtkTextureObject (0x7f9eafdb1690): failed at glGenTextures 1 OpenGL errors detected
    0 : (1280) Invalid enum

Thanks,
     Steve

Hello folks,

I was just wondering if there is a way to set an observer for a
vtkDataArray. I want to set a observer for a vtkDoubleArray (for example)
and when the object change it will call a function in python. Does anyone
know a way to do this?

Hi Steve,

Here is some code that I use to bind a VTK window to a QWidget.  My guess
is that something similar should work with GTK.  I have been using this on
OS X with vtkCocoaRenderWindow.

void BindRenderWindow(vtkRenderWindow *window, QWidget *widget)
{
  // Unmap the window if it is already mapped somewhere else.
  if (window->GetMapped()) {
    window->Finalize();
  }
  // Create the connection
  window->SetWindowId(reinterpret_cast<void *>(widget->winId()));
  // Note that we must call the superclass SetSize()/SetPosition()
  // (we just want to set the member variables, with no side-effects)
  window->vtkRenderWindow::SetSize(widget->width(), widget->height());
  window->vtkRenderWindow::SetPosition(widget->x(), widget->y());
  // Prepare for rendering
  if (widget->isVisible()) {
    window->Start();
  }
  // Call SetSize() again, to synchronize the window to the widget
  window->SetSize(widget->width(), widget->height());
}

Some further notes:
1) I disable Qt's paint engine, so that Qt itself doesn't draw in the
window.  GTK may be similar.
2) You probably will not need GtkGLExt (for Qt, I didn't have to use
QGLWidget).

Is this the 32-bit modified counter overflow problem?

What version of VTK?

I tried to use
AddObserver(vtkCommand::ModifiedEvent, ...)

but when I add a value into the vtkDataArray the observer doesn't work, I
have to explicit call the method Modified(), there is another way to do
data? I just want to call a function after the vtkDataArray is modified
like when I insert a value or remove it.

Thanks in advance.

I recall that the data arrays do not change the modified time because
of efficiency. You can explicitly call Modified each time you add a
value.

Yes, that?s the one. If the version of VTK you are using pre-dates that fix, it seems likely to be the culprit here. Hopefully you can update VTK to a build which includes the fix, and the problem should go away.

HTH,
David C.

Subject: [vtkusers] transform filters and axes
Message-ID: <CADnb_XJ8wYo8FvYLm94whj+vcpB=BRP8ihkwXo3wTeXV49654Q@mail.gmail.com>

Hi,

I'm plotting some data via a 2d rectilinear grid reader.

I am applying a transform to the reader output which scales the data via
vtkTransform.Scale.

I also have a vtkCubeAxesActor which is not scaling.

I am wondering, do I need to set up a separate transform for
vtkCubeAxesActor, or can I pipeline output from the already instantiated
transform. In either case I am unsure as to how to make the connection.

I am also wondering if there is a max height/width scaling option I can
feed to the scaling transform so the plot and axes take up all the
available space in its window.

Thanks,

Nick

Subject: [vtkusers] vtkHardwareSelector select wrong points!
Message-ID: <1508985312247-0.post@n5.nabble.com>

Hello everyone,

Recently, I am developping interactive selection function in render view
base on VTK. In order to select visible cells and points, I choosed
vtkHardwareSelector after I run this example  *
<https://cmake.org/Wiki/VTK/Examples/Cxx/Filtering/ExtractVisibleCells>
"VTK/Examples/Cxx/Filtering/ExtractVisibleCells"* . In my program,
vtkHardwareSelector works very well for selecting visible cells. But when it
comes to selecting points, something wrong happened, as showing in below
pictures, the points that are not in select zone are choosed.
<http://vtk.1045678.n5.nabble.com/file/t341092/selectionZone.png> 
<http://vtk.1045678.n5.nabble.com/file/t341092/PointSelection.png> 

Then, I test this function in ParaView(v5.1.2 windows 64 bit) as Paraview
also uses vtkHardwareSelector to select visible cells and points. but when
selecting points, the same wrong results are showing in below pictures.

<http://vtk.1045678.n5.nabble.com/file/t341092/paraviewSelectZone.png> 
<http://vtk.1045678.n5.nabble.com/file/t341092/paraviewSelectResults.png> 

testPolyOut.vtp
<http://vtk.1045678.n5.nabble.com/file/t341092/testPolyOut.vtp>  
the test file I used is also attached.

I have searched the mail list, but I can not find any valuable information
about this problem. Could anybody know hows to solve this proble give me
some help? Thanks very much!

Best wishes,

Jie

Hi all,

I wrote a Python script that applies a collection of mathematical
tilings to user-defined 2D manifolds:

https://github.com/cwant/tessagon

I originally wrote it for Blender, but since very little of the code
is Blender-specific, I also added an 'adaptor' to the script to
generate VtkPolyData.

Check it out if you're into that sort of thing!

Hi!

Take a look at the following code, why is the lookup table resulting
from a merge not copied? Number of inputs added doesn't seem to
matter.?
Is that intentional or is it an oversight?

Thanks!

vtkSmartPointer<vtkPoints> points = vtkSmartPointer<vtkPoints>::New();

points->SetNumberOfPoints(3);

points->SetPoint(0, 0.0, 0.0, 0.0);

points->SetPoint(1, 1.0, 0.0, 0.0);

points->SetPoint(2, 0.5, 1, 0.0);

vtkIdType cellIds[3] = { 0, 1, 2 };

vtkSmartPointer<vtkCellArray> cells =
vtkSmartPointer<vtkCellArray>::New();

cells->InsertNextCell(3, cellIds);

vtkSmartPointer<vtkLookupTable> lut =
vtkSmartPointer<vtkLookupTable>::New();

lut->SetRange(0, 1);

vtkSmartPointer<vtkIntArray> testPointData =
vtkSmartPointer<vtkIntArray>::New();

testPointData->SetName("TestPointData");

testPointData->SetLookupTable(lut);

testPointData->InsertNextValue(0);

testPointData->InsertNextValue(1);

testPointData->InsertNextValue(2);
? ??

assert(ugrid->GetCellData()->GetArray("TestCellData") != nullptr);

assert(ugrid->GetCellData()->GetArray("TestCellData")->GetLookupTable()
!= nullptr);

vtkSmartPointer<vtkUnstructuredGrid> ugrid =
vtkSmartPointer<vtkUnstructuredGrid>::New();

ugrid->SetPoints(points);

ugrid->SetCells(VTK_TRIANGLE, cells);

ugrid->GetPointData()->AddArray(testPointData);

vtkSmartPointer<vtkAppendFilter> append =
vtkSmartPointer<vtkAppendFilter>::New();

append->AddInputData(ugrid);

append->Update();

vtkUnstructuredGrid* outgrid = append->GetOutput();

assert(outgrid->GetNumberOfCells() == 1);

assert(outgrid->GetNumberOfPoints() == 3);

Hi Andrew -
One potentially easy thing is to use the newest VTK release - performance
often improves between releases.
I see one noob mistake :) ImmediateModeRenderingOn() doesn't do anything
with current VTK - everything is shader-based.

I can see that you are dynamically changing the size of the entire dataset,
to add a small number (~360) of points. I would definitely consider
dividing the points up into batches, so that you are adding points to a
much smaller set. I mean several vtkPoints() and vtkCellArray() instead of
one.

I believe you might also be able to pre-allocate the expected size of the
set, but I'm not sure how to do that?

Aron

Hi,

I use VTK-8.0.0 and I'm setting vtkContextInteractorStyle.
But I have a problem,

vtkSmartPointer<vtkContextInteractorStyle> style =
            vtkSmartPointer<vtkContextInteractorStyle>::New();

contextView->GetInteractor()->SetInteractorStyle(style);

this code has error at SetInteractorStyle(style).


Other interactor style classes doesn't occur error.
Why only in my case has error?
And how should i change my code?

Thanks Aron,

I will try and use SetPoint for my point insertion, 

When You say break it up into Pieces do you mean have multiple Polydata
actors and Mapper? as they reach their respective "max size" make a new one
and add it to the scene?? My newest attempt uses Pieces that are added onto
make 1 large poly data using The vtkAppendPolyData with its Mapper and
actor.

I can see the renderWindow is an openGL window and my GPU does get utilized
but, like I mentioned, as the set grows its the render event that takes
longer and longer not that addition of a point 360 points (2ms)

Regards Andrew

I want to reslice the m_spVtkImageData to make it isotropic, as 0.4*0.4*0.4.
However, when I use MIP to show this resliced image, it suggests that there
must be some problems. What's wrong with that?

You cannot share actors across renderwindows right now.

I encounter the same problem. So I try to display my point cloud with raw

It looks like an integer overflow problem.  Perhaps the data is "unsigned
short" but was read as "short"?

Just in case the Cubic interpolation is causing overflow (since cubic
interpolation has undershoots/overshoots), try linear interpolation:

resliceFilter->SetSlabModeToMaximum();
resliceFilter->SetSlabNumberOfSlices(3);
resliceFilter->SetInterpolationModeToLinear();

Hi Andrew,

Typically 'break it up into pieces' means create multiple vtkPolyDatas and
put them into a vtkMultiBlockDataSet.  With your current solution using
vtkAppendPolyData, the entire points list has to be recomputed every time
you add more to the vtkAppendPolyData and then that new list has to be
uploaded to the GPU for rendering (this also probably deallocates the old
one and allocates a new buffer with the new size too).  You could break it
up into many vtkPolyDatas and have an actor and mapper for each of them,
but typically it is more efficient to put them in a vtkMultiBlockDataSet
and use the vtkCompositePolyDataMapper2 to render them all at once (that
said I'm not sure about performance in this case where you are modifying
it, others on the list may know more about the implementation and how it
will perform).

HTH,
Shawn

Right now duplicate the actor and mapper. You can use the same polydata
input just not the same actor/texture/mapper.  In the future we plan to
change this so that multiple render windows can share contexts (and
actors/mappers/etc) but it is still in development.

thanks Martin, but if I want to show the same data in multiple renderwindows, how should I do normally ?

Hi David,

I have finally got some time to have a quick revisit of this (was that
really a year ago!).

Long story short, I simply can't seem to get it to do anything. I have tried
inserting an OSPRayPass into the renderer (following the pattern in the
OSPRay tests), and I have also tried using vtkOSPRayVolumeMapper directly
instead of vtkSmartVolumeMapper. I should note that the pipeline I am
testing with works fine with the GPU based renderer.

I am using the latest OSPRay and embree builds from their respective
websites on Windows and VTK 8.0.1 built using VS 2017.

As far as I can see, I am getting a std::runtime_error exception in
vtkOSPRayRendererNode.cxx, line 432:

  OSPData lightArray = ospNewData(this->Lights.size(), OSP_OBJECT,
    (this->Lights.size()?&this->Lights[0]:NULL), 0);

The Lights array looks fine in the debugger with one entry as expected.

Are there any gotchas you know of that are likely to cause this? I am a bit
stuck presently.

Thanks
Ian

To get volumetric shadows everything in the renderer has to be rendered by
ospray (i.e. just stick an OSPRay pass into your renderer and let it take
over).

The osprayvolumemapper option (both directly and within smartvolumemapper)
makes ospray responsible for rendering only that one volume within and
otherwise openGL rendered scene. It won't produce shadows on the GL
rendered data. It should otherwise work though, and without seeing your
code I can't guess from what you posted what is going wrong. Try running
the ospray related tests in your VTK build (ctest -R OSPRay) to diagnose
the setup further.

Another note - if your data is unstructured grid, neither ospray volume
rendering path will display anything unless you resample to image data.
That limitation will be removed in the next couple of days as OSPRay 1.4
now has support for unstructured grid volume rendering.

Hi,
have you tried playing with ISOvalue?

This discussion thread might help you :
https://stackoverflow.com/questions/43682388/thick-surface-with-vtk

I also vote for having such a filter embedded in VTK. This will be simply
great..

I am wondering, if something like this exists in ParaView (posting this
thread to PV mailing list too)


Thanks and regards,
Chiranjib

Subject: [vtkusers] Why can't I warp vtkCubeSource ?|
Message-ID: <1509148532114-0.post@n5.nabble.com>

I need  to apply kind of  "pinch" to vtkCubeSource, to make it look like half
cylinder. I have thought to use warpScalar for that, however, no matter what
I try I just can't get it working. The cube remains exactly as it was.

Can anybody  spot a problem in my code? Thanks,
AC

void warpTest()
{
	vtkSmartPointer<vtkCubeSource> cubeSource =
vtkSmartPointer<vtkCubeSource>::New();
	cubeSource->SetXLength(50);
	cubeSource->SetYLength(10);
	cubeSource->SetZLength(1);
	cubeSource->SetCenter(0,0,0);
	cubeSource->Update();
	vtkPolyData* polydata = cubeSource->GetOutput();

	vtkSmartPointer<vtkDoubleArray> scalars =
vtkSmartPointer<vtkDoubleArray>::New();
	polydata->GetPointData()->SetScalars(scalars);
	int numOfPoints = polydata->GetNumberOfPoints();
	scalars->SetNumberOfTuples(numOfPoints);
	for (vtkIdType i = 0; i < numOfPoints ; ++i)
	{
		scalars->SetTuple1(i, 200);
	}

	vtkSmartPointer<vtkPolyDataNormals> normalGenerator =
vtkSmartPointer<vtkPolyDataNormals>::New();
	normalGenerator->SetInputData(polydata);
	normalGenerator->ComputePointNormalsOn();
	normalGenerator->ComputeCellNormalsOff();
	normalGenerator->Update();

	vtkSmartPointer<vtkWarpScalar> warpScalar =
vtkSmartPointer<vtkWarpScalar>::New();
	warpScalar->SetInputData(normalGenerator->GetOutput());
	warpScalar->SetScaleFactor(1); // use the scalars themselves 
	warpScalar->Update();

	vtkSmartPointer<vtkPolyDataMapper> mapper =
vtkSmartPointer<vtkPolyDataMapper>::New();
	mapper->SetInputConnection(warpScalar->GetOutputPort());

	vtkSmartPointer<vtkActor> actor = vtkSmartPointer<vtkActor>::New();
	actor->GetProperty()->SetColor(1.0, 1.0, 0.0);
	actor->SetMapper(mapper);

	vtkSmartPointer<vtkPolyDataMapper> smapper =
vtkSmartPointer<vtkPolyDataMapper>::New();
	smapper->SetInputData(polydata);

	vtkSmartPointer<vtkActor> sactor = vtkSmartPointer<vtkActor>::New();
	sactor->GetProperty()->SetColor(1.0, 0.0, 1.0);
	sactor->SetMapper(smapper);

	// Visualize
	getRenderer()->AddActor(actor);
	getRenderer()->AddActor(sactor);

Subject: [vtkusers] How can I set bounds for vtkLinearExtrusionFilter
Message-ID: <1509274900848-0.post@n5.nabble.com>

I need to implement the free hand mesh cutting in VTK. I implemented it using
a custom cutting filter, derived from vtkPolyDataAlgorithm.

This filter gets the points drawn by user, projects them on a plane, and
uses the resulting vtkPolyData to create a vtkLinearExtrusionFilter.

It works pretty good on simple meshes like a cube or a sphere, but if the
mesh is a table, for ex., when I try to cut one leg, all legs are cut,
because the extruding object is endless, and I don't know how to limit it to
one leg only.

So the question is: how can I set bounds for vtkLinearExtrusionFilter?

There is a lot of code involved, I can post any fragment of it per request,
or upload it somewhere and add the link if the need be.

Hello,

I am facing the same problem about using the  ColorByArrayComponent, which
always default the first array source even if I changed the array source
name. So, did you solve this problem and may you tell me how to do?

Thank you very much in advance!
Jane

To fundamentally change the shape from a cube, you'll need to discretize
the cube to have more than just the 6 faces that define the initial cube.

First, triangulate the cube with vtkTriangleFilter, then use
vtkLinearSubdivisionFilter to add triangles. You should have better luck.

Message-ID: <CAHS0xYYcoZgAPMLUNOZff+qVSOF6Ab7ccu8eJNxUUiS4fQHRdQ@mail.gmail.com>

Hey guys,

I just install an AWS EC2 instance running on Windows Server 2016 with
Tesla K80. While trying to install VTK through Github, I find out the Open
GL library is missing and preventing me to complete the installation. After
I install the OpenGL, I still cannot access its library as the Nvidia CUDA
driver is taking the control. Can anyone help me to resolve this issue? Or
should I just launch another EC2 instance without the GPU instance?

Thanks a lot, I will give it a try. I have already figured out the
triangulation part, but weren't aware of the need to apply
vtkLinearSubdivisionFilter .

Message-ID: <AM5PR0601MB23061DC44BF9BE9777AEFC03C0590@AM5PR0601MB2306.eurprd06.prod.outlook.com>

Hi,


I'm currently porting an existing finite element mesh analysis application from VTK 7.0 to VTK 8.x (actually the last master to be ready for the upcoming 8.1 version). But when switching to the new QVTKOpenGLWidget, I encountered too issues, one relatively minor, the other pretty annoying.


The first and biggest problem is selection, both using vtkHardwareSelector from surface selection, and the vtkRenderedAreaPicker for frustum selection. The vtkHardwareSelector sometimes simply fails to select the points properly, whereas it always worked with the previous QVTKWidget. Unfortunately, it's very random, and I can't manage to get a working example showing the issue on each selection. For the vtkRenderedAreaPicker, the problem is that the render window becomes black while the picker is working.


The second and minor issue, the first I encountered, concerns a transparency problem with the new widget rendering. Lines seems to blend with the background. I opened an issue here for that one: https://gitlab.kitware.com/vtk/vtk/issues/17154. It's not as important as the selection bug, but it was the first issue I saw. It is only visible when multisampling is enabled.

I knew how to solve this problem, add the code
"reader->SetReadAllScalars(1);" before "reader->Update();", then I can color
the actor with other scalar data arrays. Good luck for you guys!

My problem: I have a pattern image in PNG format that I want to project onto a 3D object. I believe this is the right class to use. If this not the right class to use, can you please point me to the appropriate class?

I have had exactly the same problem with this code:

	vtkRenderer* renderer = vtkRenderer::New();
	renderer->SetBackground(0.0, 0.0, 0.0);
	vtkRenderWindow*	renderWindow = vtkRenderWindow::New();
	renderWindow->AddRenderer(renderer);
	vtkRenderWindowInteractor*	renderWindowInteractor =
vtkRenderWindowInteractor::New();
	renderWindowInteractor->SetRenderWindow(renderWindow);

	coneSource->Update();
	vtkPolyDataMapper*	coneMapper = vtkPolyDataMapper::New();
	coneMapper->SetInputConnection(coneSource->GetOutputPort());
	vtkActor*	coneActor = vtkActor::New();
	coneActor->SetMapper(coneMapper);
	coneActor->GetProperty()->SetColor(1, 1, 0);

	renderer->AddActor(coneActor);

	vtkInteractorStyleTrackballCamera*	style =
vtkInteractorStyleTrackballCamera::New();
	renderWindowInteractor->SetInteractorStyle(style);

	vtkAxesTransformRepresentation*	representation =
vtkAxesTransformRepresentation::New();
	vtkAxesTransformWidget*	transformWidget = vtkAxesTransformWidget::New();
	transformWidget->SetInteractor(renderWindowInteractor);
	transformWidget->SetRepresentation(representation);
	transformWidget->On();

	renderer->ResetCamera();
	renderWindow->Render();
	renderWindowInteractor->Start();

However, if I move *transformWidget->On()* to be the last line, 
after *renderWindowInteractor->Start() 
*
the problem disappears. Looks like a bug to me, as it makes the widget
pretty useless.

Hello there,

I upgraded VTK from 6.3 to 8.0, and tried to execute some legacy code implemented on 6.3. However, after setting up the project include and lib dirs in VS2015, it threw some errors like:

Severity Code Description Project File Line Suppression State
Error LNK2001 unresolved external symbol "void __cdecl vtkRenderingOpenGL_AutoInit_Construct(void)" (?vtkRenderingOpenGL_AutoInit_Construct@@YAXXZ) test_vtk D:\develop\C++\projects\test_vtk\test_vtk\test_vtk\Vis3D3Phase_WithPipe.obj 1

My code starts like:
#pragma

#include <vtkAutoInit.h>
VTK_MODULE_INIT(vtkInteractionStyle);
VTK_MODULE_INIT(vtkRenderingOpenGL);
VTK_MODULE_INIT(vtkRenderingVolumeOpenGL);
VTK_MODULE_INIT(vtkRenderingFreeType);

#include "vtkSmartPointer.h"
#include "vtkImageData.h"

It seems libs are not recognised, but I did update all relating parameters in VS project properties.


In addition, I tried the example of vtkShadows, but unfortunately it said unresolved header file "vtkFrameBufferObject.h".

Any tips would be appreciated!

Cheers,

Chiang

Hi Chiang,

VTK's default rendering implementation changed from VTK 6 to VTK 7, so the
library names you need changed.  The OpenGL backend worked with OpenGL
1.1(or 1.2?), and the newer OpenGL2 backend uses OpenGL 3.2.  The default
changed to OpenGL2 in VTK 7.0 and so you need to update the names of the
libraries you are using from vtkRenderingOpenGL and
vtkRenderingVolumeOpenGL to vtkRenderingOpenGL2 and
vtkRenderingVolumeOpenGL2.  There is a script you can run in the VTK source
tree (Utilities/Scripts/WhatModulesVTK.py) to figure out what modules you
need to use.  I'd run that script and see what you get since I'm not sure
if anything else you use has changed.

HTH,
Shawn

The data I am using is straightforward 16 bit signed CT data, no unstructured
grids. I believe I saw that support for this had been added recently to
OSPRay. I have put the following code in to add the render pass
(rendererToAddTo is a vtkRenderer):

vtkSmartPointer<vtkOSPRayPass> osprayPass =
vtkSmartPointer<vtkOSPRayPass>::New();
rendererToAddTo->SetPass(osprayPass.GetPointer());

With this commented out, the volume renders fine with the GPU renderer, so I
am fairly sure the rest of the pipeline is ok.

With these lines in place, I get the same exception when the light array is
created. Unfortunately, I am testing this in an existing class hierarchy, so
giving you the pipeline code may be a bit tricky as the code is in various
places. The light is just the default one (follow camera?) that vtk adds
automatically.

I have managed to run the tests as you asked in your previous message and
all seems fine (rendered images appear) until the final two. These look to
'half render' an urn with a grey rectangle below. The output is as follows:

I believe VTK can handle this but there are pitfalls if you want to have
huge distances combined with small scale local details. Basically create
two renderers on top of each other render the large scale first in one then
the small scale second on the other with SetTransparent(1). If your large
scale data goes in front of your small scale then it gets trickier as you
would need to use the zbuffer from the large scale as a texture with a
modified shader in the small scale. The details of which would not be a
short email.

Hello Shawn,

Your tips really help! But I cannot find the script under the dir as you mentioned. I wonder it has been moved to somewhere else in VTK 8.

Best wishes,

Chiang

Hi Chiang,

VTK's default rendering implementation changed from VTK 6 to VTK 7, so the library names you need changed.  The OpenGL backend worked with OpenGL 1.1(or 1.2?), and the newer OpenGL2 backend uses OpenGL 3.2.  The default changed to OpenGL2 in VTK 7.0 and so you need to update the names of the libraries you are using from vtkRenderingOpenGL and vtkRenderingVolumeOpenGL to vtkRenderingOpenGL2 and vtkRenderingVolumeOpenGL2.  There is a script you can run in the VTK source tree (Utilities/Scripts/WhatModulesVTK.py) to figure out what modules you need to use.  I'd run that script and see what you get since I'm not sure if anything else you use has changed.

HTH,
Shawn

Hello there,

I upgraded VTK from 6.3 to 8.0, and tried to execute some legacy code implemented on 6.3. However, after setting up the project include and lib dirs in VS2015, it threw some errors like:

Severity Code Description Project File Line Suppression State
Error LNK2001 unresolved external symbol "void __cdecl vtkRenderingOpenGL_AutoInit_Construct(void)" (?vtkRenderingOpenGL_AutoInit_Construct@@YAXXZ) test_vtk D:\develop\C++\projects\test_vtk\test_vtk\test_vtk\Vis3D3Phase_WithPipe.obj 1

My code starts like:
#pragma

#include <vtkAutoInit.h>
VTK_MODULE_INIT(vtkInteractionStyle);
VTK_MODULE_INIT(vtkRenderingOpenGL);
VTK_MODULE_INIT(vtkRenderingVolumeOpenGL);
VTK_MODULE_INIT(vtkRenderingFreeType);

#include "vtkSmartPointer.h"
#include "vtkImageData.h"

It seems libs are not recognised, but I did update all relating parameters in VS project properties.


In addition, I tried the example of vtkShadows, but unfortunately it said unresolved header file "vtkFrameBufferObject.h".

Any tips would be appreciated!

Cheers,

Chiang

Ok, Looks like the light creation exception was a red herring. This was due
to a rogue old opsray dll in my debug directory (presumably from an earlier
attempt at getting this working). I have removed this and verified that the
correct dlls are getting loaded with Depends.

I am still seeing a black image, but now no exception or debug output. Are
there any areas I could look at to try to get to the bottom of this? Am I
right in expecting the LUTs, etc that I am using for the GPU render pathway
to function in the same way for OSPRay (just with ray traced results rather
than ray casting)?

Message-ID: <2092576104.17789861509487957599.JavaMail.httpd@fep-webmail-04>

Hello everyone,
some updates about the solution to the problem.I have managed to upgrade my CMake to version 3.10 and I successfully built VTK 8.0.1. However, in the last few days I have been facing a new problem. When I try to include QVTKOpenGLWidget I get the following error: "Cannot locate QOpenGLWidget.h"
I have seen on the web that other people had the same problem, but despite my efforts I did not succeeded in solving it. I am using Qt 3.4.2 based on Qt 5.5.0, so there should not be any problem, since in the QOpenGLWidget has been introduced in Qt 5.4.0.
Do you have any idea why this happens? Could the error be in the CMakeFile.txt of my project or should I look into the build configuration of my Qtcreator?
I hope I am not too off-topic, but solving this problem could be useful for other people (and all these problems are somehow connected).
Thanks a lot for the help.Best,Luca

Luca, I haven't looked into your problem/thread in detail, but I have one suggestion that might come useful: are you maybe at some point doing things in a secondary thread, and somehow passing data to your widget from this thread?It has happened to me in the past, and the GUI would temporarily switch to drawing in black or not updating any more.If you are using background threads, look into this.Best,AlessandroOn Oct 17, 2017, at 5:23 PM, bartolomei-luca at virgilio.it wrote:Thanks to everyone for the inputs.I will try to include the QVTKOpenGLWidget in my project. I will let you know if I succeed in doing that and if this solve the issue. at Shawn -> About the Cmake: I can successfully build VTK 8.0 and use it in QT if I use a newer version of cmake (currently, the default cmake version for my system is 3.2.2). The problem is that I cannot build my project with VTK 8.0 using ROS. So the problem is not Cmake itself, but the version ROS uses for building (too "old" for VTK 8.0). I will try also to fix this.For the moment, thanks to all. I will let you know in case of success/failure.Best,Luca

When one of the projects I work on first started using Qt5 with VTK we had similar problems.  Embedding a QVTKWidget in a Qt5 Tab or Scroll widget or using it alongside other OpenGL-based widgets in Qt5 can cause these kinds of issues and this was the motivation for creating the QVTKOpenGLWidget.  The QVTKOpenGLWidget correctly lets Qt manage the OpenGL context rather than hacking it in with window system calls.  You could try grabbing the QVTKOpenGLWidget code from VTK 8.0.0 and copying it into your project as a temporary solution (I'm not sure if it relies on any features added between 7.1 and 8.0).You said upgrading CMake was blocking you from using more recent VTK?  The CMake developers try really hard to be backwards compatible.  Have you reported the issues you are having to them?  I know they try their best to handle compatibility issues that are reported.HTH,ShawnOn Tue, Oct 17, 2017 at 10:03 AM, Sankhesh Jhaveri <sankhesh.jhaveri at kitware.com> wrote:How are you initializing the QVTKWidget?One other thing to test would be to try removing the QTabWidget and showing both the QVTKWidget and QWidget in the same central widget side-by-side. Finally, you could see if the setup works fine with Qt4.I am not sure how you would put a GLUT window inside a QWidget. But if you have can do that, you could try the vtkExternalOpenGLRenderWindow. See TestGLUTRenderWindow.cxx for an example.

Then:At the moment the two widgets are under the central widget (a QWidget). They are in two different tabs of a QTabWidget. I tried to move the QVTKWidget out of its tab but no luck. I have also noted another thing. If I show at the same time the QWidget and the QVTKWidget, the QVTKWidget works fine, but the QWidget freeze. That's why I thought that it could be an OpenGL context issue.What do you mean by "replacing ROS widget with a simple button"? In any case, I can make QVTKWidget work, but no success with the QWidget. It just freeze on the last view.Unfortunately, QVTKOpenGLWidget is available only for VTK 8.0 and higher. I am using VTK 7.1 and I cannot upgrade to 8.0 because of the cmake that is installed on my laptop. I cannot upgrade the cmake version due to some compatibility issues with ROS. I will get in a lot of trouble if I try to do that. Is there a way to use glut or vtkOpenGLRenderer (available in vtk 7.1)?Thanks a lot again for the help.Best,Luca

Hi Luca,

Do the QWidget and QVTKWidget overlap at all or are they separated by some QFrame border, etc. ? If they are not overlapping, it means they are not sharing the OpenGL context.

Have you tried replacing the ROS widget with a simple button to see if the QVTKWidget works properly?

Lastly, the QVTKWidget is known to have rendering issues with Qt5. Try using the QVTKOpenGLWidget to see if anything changes.

Best,Sankhesh

I don't know, but it sounds like it's possible. I think there are
other people on this list who knows much more about OpenGL and how VTK
uses it than I do, so I'll let those answer that.
